Plot hole: In the makeshift morgue when Simon and Matthew first fight the vampires, Solina is shot and pinned to the wall with a large silver nail and remains calm and unaffected. However, moments later Marcus is fighting with Simon and grabs one of same kind of nails but must drop it when it burns his hands. It makes no sense that Solina had no adverse reaction to the nails at all when Marcus reacted so violently. (00:42:00 - 00:57:50)
Plot hole: In what appears to be at least an hour or so after curfew is put in effect, Challis goes to a liquor store. Even if he didn't know about the curfew, why would the liquor store still be open?
Plot hole: When the policeman asks Kirsty at the beginning who came when she solved the box she says the Cenobites; she had no way of knowing what they were called. Frank only told Julia; Kirsty didn't hear it anywhere and the Cenobites themselves didn't tell her either.
Plot hole: The Hellworld website at the beginning of the film has eerie music and also Pinhead's voice reciting some of his famous lines from other Hellraiser movies, which is impossible; there's no way that someone could have gotten recordings of those moments in the past where he said the lines, so they couldn't be playing on an internet webpage.
Plot hole: In the scene where Katrina is watching through Valek's eyes as he kills father Molina, Crow orders father Giteau to "find out where an old padre is missing". But Katrina never described father Molina, all she said was "He killed the priest". Crow could not have known the age of the man who was killed.
Plot hole: At the end of the movie where David and his friends are attempting to break into Steve's house, David has the door code and attempts to gain access once by using it. Steve then tells his wife and the kids to go hide upstairs and turn off all the lights so nobody will know where they are. Then Steve and his wife go to another part of the house, away from the front door. Then, we hear David and his friends using axes and a big log to try and break down the door, "before* Steve secures the door with household appliances later on. Why wouldn't David have just kept trying the code?
Suggested correction: The reason David can not keep trying the code, is because the door has a lock on the top, and one at the bottom (middle regular lock). That middle lock is able to respond to the key/pass-code system, but the top one is not. In order to get in the house, David would have to be able to enter the pin (which, yes he knows) but with the top lock still locked from the inside he can not get in. I am assuming there is a key slot on the outside where he would need a key, and also I'm sure the family doesn't bother locking the top half of the door as no one else knows the pin (so they thought). And I'm guessing that they never locked it during the day either, and only at night.
Plot hole: The aliens seems to be very strong, but not using technology at all. How come they defeated for example tank units? Doesn't look like they can penetrate steel with their arms.
Suggested correction: The aliens also demonstrate the ability to run extremely fast, easily able to outmaneuver a slow-moving tank. They would most likely jump on the top of the tank or rip the treads off, considering they still are extremely strong. They would also quickly jump onto a helicopter and take it down. As for other vehicles such as jets or aircraft carriers, the aliens either would have attacked military bases or taken the fight out to sea in ships. Whatever the answer, that particular element of the aliens is a large amount of possibilities, not a mistake.
If a waterfall can disorientate them, so would a jet engine or gunfire.
Loud sound doesn't disorientate them; it just "hides" quieter sounds.
Something they teach in the military is the "ghost walk" - how to move silently. As the newspaper cuttings suggest, the noise angle was known about while there were still working printing presses, so it must have been a slow event. And a helicopter gunship can engage from up to 1km away, that's a long jump.
Yeah, how does the military never tried to use loud and/or high sound to defeat them once they found that they hunt using the sound? But to be fair they seem to be everywhere, so maybe they attacked in very large numbers.
That's actually clever (assuming the aliens didn't rip everything apart before coordinated strikes). Have some jets fly at low speed and A10s behind light up the space.
Plot hole: When Ripley goes to access the computer Mother, the entry door opens and closes with a hissing noise, a couple of minutes later you see Ash next to Ripley with a smile on his face. How did Ash manage to open the same door without it making the hissing sound? Ash could not have been in the room before Ripley came in - once Ripley has sat down at the console, it rotates on a 90 degree angle, this would have made it impossible for Ash to be hiding behind a desk or a computer console without being seen by Ripley. There are many doors on the ship that make the same hissing sound when the doors open, an obvious example is the infirmary door. And Ash couldn't have disabled the pneumatics of the door, because when Ripley exits the room, the hissing noise is heard again. (01:18:40 - 01:20:00)
Suggested correction: There's no evidence that sound happens every time the door opens. It may be a pressure release sound, but not enough pressure has built up since Ripley opened the door to make the sound. It's like flushing a toilet twice in quick succession, before the tank has had a chance to refill. The action is the same, but the same mechanism is engaged; it makes a different sound.
Plot hole: Natalie uses her cell phone to record the injured and bleeding Chris, but it never occurs to her to use the phone to call for help? And how is it possible that in 2012, she seems to be the only one with a cell phone? It is simply not possible that she could not get a signal - the Chernobyl Exclusion Zone is festooned with mobile telephone masts - precisely because of the inherent danger of being lost there.
Suggested correction: Uri said at the beginning of the film that he has never gotten a signal whilst in that area.
Then Uri is wrong, or he is lying for some bizarre reason. The Chernobyl Exclusion Zone is festooned with mobile antenna masts and if there was one place on earth where you could absolutely guarantee getting a signal, it is there.
Plot hole: Referring to that blackout night. How come the group can actually film how they put all their cameras and stuff into its hide?
Plot hole: The psycho coed murders her lecherous professor (played by William Shatner) by pushing him out a window. In the very next scene, she's driving around with his body propped up in the passenger seat of her car. She weighed no more than 100 lbs., tops, and Shatner was easily at least 250 when this film was made. No way she could have dragged him to her car and lifted his dead weight into the seat, no matter how much adrenalin she was pumped with. Physically impossible.
Plot hole: The only reason the movie takes place is because the news station that Mrs. Mott watches names Claire as the woman who filled the lawsuit against Mr. Mott. It is completely illegal for broadcasters to name or show a picture of a sexually assaulted victim.
Plot hole: When Becky falls asleep she is awakened by Miles and has now become an alien, However she should have died and her essence should have been in one of the pods. There were none nearby.
Plot hole: When John is painting the doll's face he looks down at a photo printout of Amanda, you will notice the bruising/scratches on the side of her face in the picture. Please take note of her hair, shirt and overall demeanor. Now think back to the first Saw when Danny Glover had Amanda in the interview room. The picture that John Kramer is looking at is a picture taken of her in "that exact" interview, this is strange however considering that the interview took place after she escaped the jaw splinter, so how does John have a picture of her from the future? (00:51:40)
Plot hole: Hoffman is able to implicate Agent Strahm as the mastermind behind the main series of traps in this film by planting Strahm's cell phone at the scene. However, Hoffman is repeatedly shown to be touching things at the scene without wearing gloves, so a forensics sweep of the crime scene afterwards would show Hoffman's fingerprints all over the place and reveal him to be the actual mastermind. Agent Erickson arrives at the crime scene before the two survivors of the traps complete their tests, so the forensics team would have been called in before Hoffman had a chance to remove any evidence that would incriminate himself. As a forensics officer himself, Hoffman should know better.
Plot hole: Everybody jumps into the water and emerges on the submarine except for Natalie. They're wondering where she is when they notice a flare. They realise it's her, and they send a search party. She's hiding on a bus maybe one to two kilometres away from the water. Her going there makes no plausible sense. Makes no sense how she held her breath underwater longer than anybody that they didn't see her and why she would go in the opposite direction of the sub. It was done to prolong the scene. (01:09:00 - 01:18:00)
Plot hole: The book says the demon has to devour 5 souls in order for the abomination to return, but it only got 4 since David saved Mia's.
Suggested correction: In the extended version, we see Mia's soul isn't actually saved.
"In the extended version" has no relevance. Bonus content holds no weight when leveling criticism at the theatrical cut of a film.
Suggested correction: Actually, more than five souls were claimed over the course of the film, whether or not you count Mia. Four people died in the cabin, plus the possessed girl in the beginning of the film, in addition to the girl's mother, who is mentioned to have been killed by her. You could also make an argument that the dog counted, technically. You also gotta remember, the book said the souls must be "consumed," and technically, it did possess Mia and she "died" while still possessed before being revived. So by the vague definition of "consumed," she could still possibly count. Either way, definitely more than five souls were claimed over the course of the film.
Brother and friend were also technically cleansed by fire.
Plot hole: Despite being whipped and needing to go to the hospice afterwards to have her wounds seen to, when we see Madeleine later in the film she doesn't act as though she had whiplashes across her shoulders - she lies on her back that very night in bed, and gets up without a wince, she holds her shawl close when she is wandering around the asylum, she leans back against chairs, and in all the later scenes she is still wearing her tight bodice, despite the fact that such wounds would have been very painful for ages afterwards.
Plot hole: When Jason is going next door to chase after Trish, he pulls Jimbo's body down from the doorway and begins walking towards Trish's cabin. He is seen walking by himself. However in the next scene, he throws Rob's body through the window. There was no time for him to go back and get the body. (01:17:15)
