Plot hole: Why doesn't Reliant know that Khan is exiled here? The Federation is so terrified and opposed to genetic engineering that it's still illegal 300 years after Khan. So why is there no warning along with the data on the Ceti Alpha system? Kirk logged what happened with Khan and his solution of marooning him. Starships use nav data to navigate star systems. Ceti Alpha 6 exploded, yet the helmsman or computer never noticed that there is one less planet than there was when Kirk was there? There is no debris from the explosion? Ceti Alpha 5 is the exact same size and was conveniently blown into the exact same orbit as Ceti Alpha 6 used to have? So there is nothing whatsoever to make the crew even suspect that it's not 6? Enterprise would have to have scanned the planets in the system to know that one was habitable for Khan. Did Ceti Alpha 6's destruction somehow magically turn Ceti Alpha 5 into its exact duplicate? If Starfleet ships have been there to map after Ceti Alpha 6 exploded, none of them bothered to check on the exiles? Pretty callous for Starfleet, don't you think? With the technology and amounts of information available to Starfleet vessels, there is NO logical reason for the Reliant to think that this planet is Ceti Alpha 6. Finally, would the Federation be willing to test a device whose exact effects will be unknown on a planet so close to another inhabited one? (00:21:00)
Suggested correction: The answer is yes: against all known laws of science, the inexplicable explosion of Ceti Alpha VI led to Ceti Alpha V conveniently taking its orbit and making it easy to mistake for its former sister planet. A mistake would've been to give an explanation that can be debunked. By leaving it to "somehow" the movie leaves it open to a million possible rationalizations. You can even make a whole other story about the crazy circumstances that led to this incredible result.
Plot hole: Sarah turns up on the bridge to fight the Rev-9, we later learn that she is texted the location of where to be as when the terminators travel though time it causes a gravitational anomaly, and this is where she needs to be. The Rev-9 had been there ages killing Dani's dad etc, Sarah would have no idea to be on the bridge after the terminator has chased them though the town - she can't possibly know that location.
Suggested correction: Sarah is very skilled at fighting Terminators. She receives the coordinates but knows that many other real-world factors may impede her progress to those coordinates, so she makes efforts to prepare for that. Also, the coordinates that she received for the Rev-9 may very well have told her to fight it on the bridge because the T800 who sent those coordinates knew that Sarah would also then be able to rescue Dani and Grace, and eventually meet up with him as a result.
I'd say the real reason Sarah is on the highway to fight Rev-9 is that she followed it. She misses the moment it arrived (from the future), she follows it to the car factory, but she misses it again, then she finally catches it up on the highway.
It is explicitly stated by the T800 Carl that he was sending Sarah the coordinates of where the terminators would appear, because the arrival would create a space-time wrinkle he is able to measure ahead of time. There is no indication he can predict the future events and send Sarah coordinates of places to be other than that.
Suggested correction: Sarah's truck can be seen in the background when Grace arrives. Grace doesn't look like any Skynet Terminator, and the time bubble she arrives in is different to the ones in T1 and T2. We can infer that Sarah followed Grace from her arrival to the bridge in an attempt to understand what was going on with the new time travellers before intervening.
Plot hole: When Fluffy saves Chloe she calls out 'thank you Fluffy'. Cruella never told her the dog's name so how did she know it?
Plot hole: Radl and Steiner discuss the entire scheme to kidnap Churchill on the Alderney docks - in full view and hearing of a number of civilians (who shouldn't be there, pace another posting), including local fishermen. Though the Germans banned all fishing activities in the Channel islands including Alderney in 1941, they were well aware that there was a flow of information from the island to military authorities in the mainland. Why would they be so stupid as to discuss a top secret military mission in public? In reality, they wouldn't even discuss it in front of their own men.
Plot hole: The FBI in the movie has the ability to "blackhole" an IP address, which makes that computer unavailable to the internet. If they can blackhole the computer acting as the web server, they could also blackhole the computer acting as the name server (DNS), thereby taking down the web site and preventing additional users from connecting.
Plot hole: When the ship has turned on its side for the brief moment, it cuts to inside the ship where a hallway explodes, causing the ship to submerge. The only problem is the people are standing on the ceiling, but if the ship's on its side, they'd be on the wall, not ceiling.
Plot hole: During the end the murderer is thrown out the front window of the building. The students leave the building through the front door, but yet there is no body, and that doesn't seem to bother them!
Plot hole: Luke deliberately says he does not want to be found and came to Ach-To to die in The Last Jedi, but The Force Awakens is all about finding a map to Luke Skywalker. Why would Luke leave a map when he never wanted to be found?
Suggested correction: This is a question, not a plot hole. Luke went to find the first Jedi temple. The location of the temple is what they were ultimately needing to try and locate Luke. The map that has the temple was already created before Luke went to the temple, he did not create a map where to find him and then secretly hide it away.
It is a plot hole statement in the form of a question. It ultimately is a continuity error between Episodes 7 and 8. TFA never mentioned it as a map to a Jedi temple Luke might be at. The audience is told in that movie that it is a map to Luke Skywalker. It is believed by the end of TFA that Luke wants to be found if they needed him. It is only after Rian Johnson goes against what JJ Abrams planned for Luke that this error becomes prominent. If this is simply a map to the first Jedi Temple, then the Resistance is betting a lot on the chance Luke went there and still there after all these years.
In The Force Awakens, Kylo Ren refers to the map as a navigational chart recovered from the archives of the Empire. According to the spin-off books, the Empire were using it to find the first Jedi Temple and destroy it. So the map was not in fact left by Luke. Since Luke is believed to have gone looking for the first Jedi Temple, my guess is that whoever discovered the map realised where it led to, and knew that was where Luke was believed to have gone, and thus referred to it as a map to Luke.
What other choice do they have? The know where he wanted to go. If the do not find him there then the have someplace to look abound for clues as to where he went to afterwards. Also it is not like if he is not there they are stuck and cannot return to the resistance fleet.
A map to the first Jedi Temple is a perfectly fine explanation for what the map actually is and if the Resistance thought Luke was there, it was worth the risk to go there and look for him. However, the very identity of the map seems to change between movies and it is introduce in TFA as a map to Luke, not to a Jedi Temple. So in TFA it is a map to Luke and in TLJ it is now a map to a Jedi Temple Luke might be at. That is the problem, a discontinuity of the map's identity between the two films in the trilogy. This stems from the two directors' view of Luke in this trilogy also being completely different.
They think it's a map to Luke, or believe it, or someone else thought it was. It's not a discontinuity, just a semantic difference or miscommunication.
This movie or TFA should have explained this miscommunication as it comes across as a miscommunication to the audience and not to the Resistance. There is nothing in either film to show it is a map to a Jedi Temple Luke might be at. A miscommunication to the audience is poor writing, but since this occurs between two movies, it is a continuity mistake. This mistake is obviously due to the character of Luke changing when it moved on from JJ to Rian. This change makes the plot of TFA more confusing, but ultimately a continuity mistake is a much more just denotation for this than plot hole.
Since the Jedi Temple and Luke are in the same place the map is both a map to Luke and to the Jedi Temple. Someone looking for Luke will see it as a map to Luke, someone that is force sensitive may see it a a map to the temple.
This statement does not answer anything. The map was either designed to be a map to where Luke said he was or as map to a Jedi Temple where Luke may be. Not both. Both places can be the same, but the identity of what the map is remains as one or the other. Otherwise we are again back to a bad miscommunication in the Resistance and bad miscommunication to the audience that is just bad writing. Since it is stated in TFA that is is a map to Luke, the audience should believe it as such. It is never described as a map to a Jedi Temple Luke might be at. The continuity error and plot confusion comes from the fact that in TFA it is a map to Luke for when he was needed and in TLJ it is a map to a Jedi Temple that the Resistance hoped Luke would be at. Since TFA came first, it takes precedent and all of Luke's lines of not wanting to be found do not make sense.
While initially the audience is told it's a map to Luke, we find out later that the map leads to the first Jedi temple. This is nothing more than building suspense, which doesn't constitute a plot hole. While one could argue it was only after changes to the script or a director's choice that changed what the map was designed to be, the original mistake is still not valid because Luke never created a map to where he was going and then hide it as suggested.
Plot hole: In the final tournament when Happy is stuck in the rough, he swings five times. Assuming he hit his drive into the rough and hit an AMAZING shot from the edge of the water into the hole, he still could do no better than a seven on the hole. Happy only lost one stroke on the hole. (01:16:50)
Plot hole: The Toymaker throws that toy bird at the hippie version of himself. The toy goes through him because he is a hologram. Later, he pushes the soldier version of himself at the screen making it crack. How could he if the three others are holograms?
Plot hole: When Jake first meets Reggie, he tells Reggie that the Great Turkey told him everything about him. Later in the movie, when Reggie goes back in time and introduces himself as the Great Turkey to a young Jake, he only tells Jake to find the "Pardoned Turkey" but never said that the pardoned turkey's name was Reggie, so there's no way the adult Jake would know Reggie's name when they first meet.
Plot hole: A detective would never be assigned to a suicide scene, since suicide is not a crime. A detective would only be assigned if the suicide is actually found as a murder. Nor would a detective be assigned to find out about a potential sexual relationship or affair unless it involves a crime.
Plot hole: After his mother's death, Peter sets a camera up outside her therapist's office, so he can see who goes in and who comes out; he thinks his mother's killer might be one of the doctor's patients - a tall woman with long blonde hair. All he sees is people going in and people coming out, and then he sees her - the tall blonde. Problem: He never saw her going in, only going out, which is critical, because the killer is the therapist - a tall man - wearing a long blonde wig and make-up. Of course no-one says anything about "We never saw her going in, only out, so it must be the therapist!"
Plot hole: In the institute, Will's friend gets out of his room to get the guard's keys. He couldn't have gotten out of his room because there isn't a handle or door lock inside the room.
Plot hole: The whole point of the deception is that Fern Mayo, the geek, turns overnight into Vylett. No one at school has a clue about her real identity till Marcia and Courtney put up posters. So this deception carries on for several weeks before the two girls expose it. There is no way this would work. A school will not simply accept a new student without bothering to register her, yet when Fern Mayo just doesn't turn up to school one day, and Vylett does indeed, none of the teachers find this strange, or bother enrolling "Vylett" officially in school.
Plot hole: When the diesel train stops in the tunnel, one of the soldiers tells another one how far they are from the spot where the nuclear detonation will take place. Do the math: the distances don't work out. At least one of the trains would have to do over 100mph AVERAGE to put enough distance between them. Military precision, indeed.
Plot hole: When Superman becomes human for Lois, the molecule chamber nearly rips him apart, he suffers. At the end of the movie, when he tricks out of the evil 3 and turn them into humans with the same radiation, they are just looking around, wondering about the strange lights, but don't suffer at all.
Suggested correction: Well it's established that Superman has altered the machine. Maybe he also reprogrammed it to not leave signs of their powers being removed.
