Plot hole: As the evolved Predator's ship takes off it leaves Casey Bracket alone in hilly forest terrain. The ship then flies a long distance before crashing and the Predator and McKenna start fighting, just for Bracket to show up and help out of nowhere. Impossible for her to cover that distance that fast in hilly forest terrain.
Plot hole: The police let Norman back to his house on the same night multiple murders happened. He is even allowed into the fruit cellar, where most of them happened. (01:38:25)
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.
Plot hole: Tyler jumps into the water, then grabs his mask and puts it on and begins swimming, but he fails to clear his mask by blowing the water out of it. Without clearing it, he wouldn't have been able to see a thing.
Plot hole: The reason given for the cop having psychic powers is that he has a well-developed hypothalamus - but that is the part of the brain responsible for homeostasis (maintaining a constant internal environment for the body). So even if you had a particularly well-developed one, you might sweat more when you get hot but how could it make you psychic?
Plot hole: In one scene Eric Stoltz throws an angel out a window. This angel then lands on the roof of a parked car, bounces off as another car runs into him, smashing him against a stainless wall. Now, this is a blind street, a dead end, so why would anyone race like this?
Plot hole: Most of the story depends on Costa coming forward as a witness; however, he would have had no reason to do this. It would only make his goal of assuming others' identities more difficult.
Suggested correction: Some serial killers try to involve themselves with the investigation, for instance famous serial killer Ed Kemper.
Plot hole: Why did the killer cut off the hot water? Did he think that Dorothy would come down and turn it back on herself with all those staff members in the house?
Plot hole: When Ana is driving away from her home, she stops on the road and a guy opens her door, scaring her into turning her car toward the curb, plowing through a guardrail. She couldn't have picked up a lot of speed, and those guardrails are supposed to always be reinforced on highways/interstates. At that angle she would have had to knock out at least 4 reinforcing beams (they use 'I' beams to reinforce them, and are intended to stop vehicles from passing through them, or slow them down immensely).
Plot hole: Even if Dr. David Trent's and Annabelle Loren's elaborate plan had worked flawlessly (framing Nora Manning for Frederick Loren's death), the fact remains that they faked Annabelle's death for everyone to see, which would immediately arouse suspicions for investigators. Even if Annabelle and Dr. Trent somehow fled the scene before the police arrived the next morning, their actions would still raise many questions that implicated them; thus, their clumsy and convoluted scheme was far from being the "perfect crime" they imagined.
Plot hole: When the flying saucer first appears, it is supposed to be 4 AM. But the grave diggers are still there from the burial of Bela Lugosi's wife.
Plot hole: If Marybeth was able to seal her nostrils and use her extended finger to remove the cap and make nobody suspicious about her, why didn't Delilah do the same thing? She was alien, so she should've still been able to do it, same as Marybeth.
Plot hole: Towards the end the Rich Purgers call for reinforcements, and Shane, Leo, Eva and Cali are hiding behind a wall. A guy somehow opens a door in front of them (without being seen by the three facing him), exposes himself and shoots only Shane, numerous times, to cause his death. He should have been spotted by the people looking in his direction. Also, if he was that well hidden he could have simply sprayed the entire group. He unloaded 5 or 6 shots to Shane's chest...when he could have taken them all out.
Plot hole: When Jason is in Ginny's cabin, she's under the bed seeing where he's at. So how did Jason manage to get up on a chair and wait for her to come out without her seeing him do this? She had to see him do that, but when she pokes her head out, she's surprised to see him there.
Suggested correction: She was a bit preoccupied with the rat that got up close and personal to her. She heard the creaking, but when she looked back, she didn't see him, assuming that the sound was made by him exiting through the cabin's door. The creaking was actually him getting up on that chair, but she wasn't looking at the door because the rat was in her face.
Plot hole: How did Tommy get Jason's mask? I don't think the police would let him keep it as a souvenir.
Suggested correction: This is not the same mask from the previous movie.
Yes, it is. It even has the ax mark from the end of the third movie.
It is a very different mask. The only things that match are the shape and the axe wound. The color changed from yellow to almond. The straps changed and snap on buttons that attached the straps were replaced with rivets. The half missing large red chevron has been replaced with a red triangle. The two smaller triangles under the eyes are gone. All the damage and chipped paint from part 4 is missing. This mask has more in common with the mask in Tommy's dream in part 5. My opinion - Tommy made it.
Plot hole: Marty Mikalski discovers a micro-camera in the cabin and is immediately grabbed by the cursed zombie Judah Bruckner, who drags Marty through the window and plants a machete in Marty's back. In that shot, the machete is obviously buried in Marty's back, which should have broken ribs both back and front, severed spinal nerves, penetrated arteries (as well as the right lung), and protruded from his chest. Marty was dead on arrival in that one stroke. Yet Marty emerges at the end of the film as the hero, with no gushing blood from his back or chest or mouth, and no explanation of how he miraculously removed the machete from his back.
Plot hole: When Grace Stewart sends Ann out of the music room for "lying," the hall is visible as she opens the door - with lots of light from windows bursting in. I know it turns out not to matter, but the child would have screamed.
Plot hole: After Abe is shot, an ambulance shows up, throws Sherry in the back and leaves. There is no way that the paramedics would leave without first speaking to the police on site, making sure that no one else there needed medical help and confirming Abe was dead. I've ridden with an ambulance 4 or 5 times and they never stay at a scene less than 15-20 minutes.
Suggested correction: There's no telling exactly how his Voodoo works.
The writer/director even admitted this scene was a mistake. Prior films showed that once Chucky inhabited the doll for long enough, blood and organs would appear. The director simply chose to ignore this for this one scene, and has admitted it's a mistake.
