Plot hole: After Steven breaks out of prison, he goes to Jason's home. Then Jessica's boyfriend shows up talking on the phone and he says he will ask Jessica for permission to shoot their show at Jason's house. He should know that Jessica doesn't know she is a relative of Jason.
Plot hole: Within only a few days, cults have formed looking for fertile women? Not remotely likely.
Suggested correction: Exactly how is this not remotely likely in a fictitious horror film involving an outbreak situation (and state of emergency) that has never happened before. It's not a plot hole when irrational, terrified, or crazy people do irrational, terrifying, crazy things.
The plot hole is spot on, no way does society break down in total anarchy in just a few days, you're basically saying all law enforcement and military agencies will somehow cease to exist.
Not cease to exist, but certainly have other things to do than investigate a few random cults. Who'd to say they'd even know these cults have formed?
Plot hole: Freddy is killed at the end because he sees his own reflection in a mirror, which causes the souls in his body to revolt and kill him. But this weakness to mirrors and reflections doesn't fit in any other film of the series. He repeatedly appears in mirrors in the other films, and in the climax of "Dream Warriors," he even appears in a hallway of mirrors that are facing each other, where he would have seen his own reflection multiple times. No matter how you slice it, his death in this movie doesn't add up in the overall context of the series.
Plot hole: Karen forbids her son from playing with Chucky, because he's spending too much time with it on top of it scaring the cat, and locks it up in a cabinet. The cabinet ends up broken (Chucky broke it but she does not know), the cat conveniently disappears (Chucky killed it but she does not know), but the mother is totally cool about it, the plot point is forgotten and Andy faces no punishment or questioning for it. Any mother would be alarmed and would make a big deal of it possibly even throwing the doll away (she does not care, she did not pay for it), but that sort of drama is delayed until much later in the movie, for no internal reason.
Plot hole: Hayes continues his harassment by calling the police and provokes Drake into assaulting him. When the police come and sees Hayes injured, they take Drake away immediately without asking any questions or investigating. No law authorities would ever take away someone with mere assumptions or without investigating, regardless of a history of Drake trying to force Hayes out by shutting off the utilities. Completely unrealistic.
Plot hole: The movie establishes the narrative that megalodons have been locked beneath a layer of hydrogen-sulfide and that the first sub to penetrate that layer is their own research sub, thus allowing the megalodon to escape the hydrogen-sulfide layer for the first time in modern history. So, how could there be a megalodon present to at the very beginning of the movie, which interfered with the protagonist's rescue efforts?
Plot hole: Spoiler Alert: When Finney gets the rope that was hidden in the wall, he needs to thread it through the window bars about 8 feet above his head. After trying to lasso the rope through the bars, he grabs a rolled-up carpet and threads the rope from the bottom of the carpet through the bars and it wraps itself around the bars. There is no way a rope (or even a bendable cable) would be able to thread itself 8 feet through a carpet. After he grabs it, you can tell it's a loose rope, not a stiff wire. (00:51:15)
Plot hole: According to the detective at the end Walter believes Ray kidnapped his dog, assuming he saw the note that Ray put in Walter's mail slot. But if that note was grabbed along with Walter's mail and the wig it would have burned up along with everything else when the house exploded. So how did Walter know that Ray had his dog?
Plot hole: How would any of the EVA/16MM video footage be recovered in the first place? Astronauts took pictures like these on rolls of film, and those were developed well after the end of the flight. If the spacecraft had not been recovered at all, then the footage would simply be a piece of orbiting space junk. (01:22:40)
Plot hole: When Sid shoots the TV-show host, the number of viewers doubles in two seconds. How would all those people find out so fast and switch channels?
Plot hole: There's no way Dr. Lynn Waldheim's coat would have fitted Carter.
Plot hole: When the old women are painting the eggs, you can see them blowing the yolk out of some. Why didn't they blow the yolk out of the Critter eggs?
Plot hole: When James and Gemma arrive back at the waxwork just before the film's climax, they claim a "man with a high-pitched voice" (Hans) invited them. In the earlier scene when they decided to not enter the waxwork, they left before Hans answered the door, and he couldn't have found their phone numbers anyway.
Plot hole: The truck was in front of all of them when they turned on with the green light, but it passes them when they are stuck with the red truck. So the crash happens moments past the light, so they would all be way past that point on the interstate.
Plot hole: We learn in the film that Cat People must kill a human in order to return to their human form. However, after becoming a cat at the swimming pool and terrorising Alice, Irena becomes human again without making a kill (the only other person at the closed pool is alive and well at the end of the scene - we know Alice has not imagined the presence of the cat because of her shredded clothes). (01:31:00)
Plot hole: When Abby and her kids are abducted, the sheriff is sitting right outside her house and sees this happening. Yet the video didn't record. Well the sheriff saw it all with his own eyes so why wouldn't his testimony hold up? The tape actually shows the UFO so there's proof right there. (01:08:55)
Plot hole: Singe states that Viktor and Amelia are pure-blooded Vampires, and seems to agree when Viktor calls the story of the Corvinus Clan a legend. However, Evolution shows that Lucian had formed a partnership with Andreas Tanis, a Vampire who was outcast by Viktor specifically because he knew the truth of the Corvinus Clan and the origins of the Vampire and Lycan bloodlines. Given his lack of loyalty to the Vampires, there is no reason why Tanis would not have told Lucian that Viktor and Amelia are not pure-bloods, or that the legend of the Corvinus clan was entirely true. Lucian would have passed this information to Singe, as it would be vital to his work.
Plot hole: Interesting to note...in the opening scene where Pete is talking to Jack, Pete says that the boiler pressure needs to be dumped every night or it'll blow because the safety valve has been rusted shut for the last twenty years. Then he continues on to say that last year's caretaker, Grady, killed himself, and he was alone at the hotel. So...why didn't the boiler explode last winter? (00:02:20 - 00:05:55)
Plot hole: In the hospital scene at the end, why does Hicks run in and push Gale out of the way? She had no way of knowing someone was holding a gun on her and was about to be shot, as far as Hicks knew Gale was just standing there talking to someone. (01:40:00)
