Plot hole: The fact that a five minute timer starts after the three Cerberus codes are entered defeats the purpose of the program. If they program was made to destroy their own nuke warheads in case of a misfire you would expect them to be destroyed as soon as all three codes are in. (01:38:20)
Plot hole: Each of the four magicians are given a tarot card that has a date (March 29), a time (4:44pm), an address (45 East Evan St), and a city (NY). When they enter the building on that date, they know which apartment to go to. The problem with this is that it was never stated on any of the cards which apartment to go to once they reached 45 East Evan Street. (00:08:40 - 00:10:05)
Plot hole: They aren't able to travel before the birth of their children or their children become different. Despite that, he visits his father one last time before their third child is born. His Dad and he then travel back to when he was a kid, which would have changed his first 2 kids.
Suggested correction: This is not necessarily inconsistent with the movie's time travel logic. Since Tim goes back in time to visit his father and inside that particular time travel, they use time travel to go back to a day where Tim was a child. Then, they return back to the original time travel where they're playing ping pong. At that moment, both of Tim's kids were already born. So, when he returns from the ping pong scene, there's no change regarding his kids.
Also, paraphrasing the Dad, he said they aren't going to change anything. It is more like reliving a memory than changing the future to get what you want. The Dad couldn't go back to not smoke before his kids were born because that was major and would have changed the course of his life; walking a bit differently on a secluded beach that you walked on in your younger days (as long as you spent the same amount of time - presumably) would not alter the trajectory of one's life.
The slightest change in 1 second of being on the beach would absolutely affect his kids. A man produces 1500 new sperm every minute. Altering the timeline and delaying every event that is going to happen by literally 1 second would most definitely alter which exact sperm was used when conceiving both of his first two children.
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: The most secure prison in the world, designed with the advanced schematics of world leading prison-building architect (J.D Ray Breslin) has cameras somehow interconnected to one another so tightly that physically neutralizing one puts every other camera out of commission as well.
Plot hole: The Kaiju's EMP fries all electrical circuits next to him, and affects the base as well. If that's true, how did the helicopters carrying Gypsy survive the blast without having their electronics fried? EMP pulses induce current in all electronics regardless of whether they're powered on or not. (01:18:00)
Plot hole: The premise of the movie is that a group of this man's genetic offspring have united to learn his identity. He receives a stack of the bios of those in the lawsuit. One of the children he visits is severely disabled in a nursing facility and would not have been capable of joining the lawsuit.
Plot hole: Even if someone would make all nuclear powers launch their nuclear missiles and then destroy them you still wouldn't have a nuclear weapons free world as most of those nations have plenty of nuclear weapons in reserve. A lot would be even be armed and ready to go for a possible second strike. (01:24:10)
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: They discover a "not so well hidden" microphone in the car that tells them the "man" is listening to them, but it is ignored throughout the rest of the movie, especially when setting up a video loop to cover their extracurricular activities. (00:30:00)
Plot hole: Gerry's wife uses a rocket boot to break through a window and then slides down a curved wall to get to their son. She does so gracefully and takes off running. Gerry slides and takes a hard tumble and rolls down, landing on the ground. The next shot shows Gerry running behind his wife and not too far away as they reach their son. Even if it was to show a little time passing, there was not enough distance between where they broke the window and their son for Gerry to have picked himself up and catch up to his wife before reaching their son, especially with his wife being a worried mom doing a full on sprint to her kid.
Plot hole: How come the Extremis serum was able to regenerate Ellen Brandt's arm but not repair the scar on her face? According to the movie, the serum is supposed to rewrite the body's genetic code and constantly repair damaged cells, so her face should have been restored to its original state, just like her missing arm. Even if she had been born with the scar the serum would have healed it, just like it healed all of Aldrich Killian's physical impairments. (00:51:40)
Plot hole: After Reverse Flash saves Lois Lane and kills all the Amazons that were attacking her, he disappears, just before a group of resistance fighters shows up. They know that they didn't take out any of the Amazons, it's obvious that Lois didn't kill them, yet the resistance members show no concern as to who was responsible. The war involves three separate groups, the resistance, the Amazons and the Atlanteans, each of whom is equally hostile to the other two. As such, the resistance cannot assume that whoever killed the Amazons must be an ally and let their guard down, as it could easily have been an Atlantean force, who would make no distinction between the Amazons and the resistance and would attack them on sight. An experienced resistance team would not be so casual about the situation. (00:40:50)
Plot hole: According to the flight recording, Odyssey was on an uncontrolled pull towards the Tet as Jack says, "We're not getting away from this thing." So even if Jack jettisoned the sleep module where Julia was in, the module should not be able to get away as the whole ship is being pulled towards the Tet.
Suggested correction: It can be assumed that the jettisoned module has enough "jettison power" to force it away from the command pod. And in turn that force would move the pod further towards the Tet. It's reasonable to assume the Tet couldn't pull the module that was moving away, under dramatic force, and to which it didn't have line of sight (which was blocked by the pod).
Plot hole: When Chucky is decapitated, no blood comes out. He still has the scars from Bride/Seed of Chucky so that means he's still in the same doll's body. The longer he remains inside the doll the more human he becomes, so he should definitely bleed by this point in time.
Suggested correction: There's no telling exactly how his Voodoo works.
Plot hole: When Grug is trying to escape from the explosion behind him he sees Douglas and says "Douglas! Hey I know that guy!" This is not possible since he neither knew the name of the creature or was nowhere around when Douglas was with Thunk.
Suggested correction: Thunk might have told him who Douglas is.
Plot hole: During the warp-speed chase, the Vengeance literally blasts the Enterprise to pieces, and dozens if not scores of Enterprise crew members are killed and injured in the carnage. The medical crew, including Chief Medical Officer McCoy, should have been working feverishly on the wounded and dying for hours, at least. Instead, as Kirk asks Khan for help, the Sickbay is practically deserted, and McCoy is almost idly conducting blood experiments on a dead tribble. There's no sense of a catastrophic medical emergency whatsoever. It's as though the Sickbay sequence was shot for a different script in which there was no emergency, and then lazily inserted into a rewritten script.
