Revealing mistake: When the pastor is beheaded you can see a clear tube inside his neck that is squirting blood.
Suggested correction: That's actually supposed to be the top of his spinal cord. The blood is noticeably coming from behind it if you look closely.
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.
Factual error: Chucky is not tall enough to rev the engine of the car in the garage when trying to suffocate Nica.
Suggested correction: I watched the scene and it's clear Chucky wasn't using a brick on the accelerator to rev the engine. However, Nica is paralyzed and there are devices you can install on a car that allows a paralyzed person to operate the gas and brake from the steering wheel, so Chucky could rev the engine without touching the gas pedal.
Suggested correction: All he would have to do is stand on the gas pedal.
He's standing at the wheel the entire scene. He's not tall enough to be doing that and pressing the gas pedal.
He could have used a brick or something to keep the gas pedal down and then climbed up to the wheel.
Except if you watch the scene, the engine revs up and down, not something putting a brick on the gas pedal would do.
Continuity mistake: When Chucky pushes Nica over the balcony, the camera shows her falling to the floor on her back but when the camera zooms out on her, it shows her lying on her stomach.
Suggested correction: You don't see her land, and she's off-screen for a solid 15 seconds. It's entirely possible she hit the ground and rolled onto her stomach.
