Plot hole: Following Glen's death, Nancy tells her father to come across the street in 20 minutes to catch Freddy. She then goes to her house, checks and sets her alarm clock, and proceeds to rig the entire house with booby traps, including filling a light bulb with the contents of several shotgun shells, and has a heart-to-heart talk with her inebriated mom. When she gets back to her room to go to sleep, she checks her clock again. The time on the clock has advanced only ten minutes, not nearly long enough for everything she did.
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)
Plot hole: The whole film is basically told as a flashback from Rand Peltzer's point of view. Now he might be able to talk about things that Billy, his mom, or Kate might have told him, but he wouldn't have known about all the other the gremlins did to the rest of the town like killing Mrs. Deagle, the cops, or the gremlin in the mailbox.
Plot hole: Captain Bosch and AJ steal George Cooper's photos, but not the negatives. George Cooper discovers the photos are missing, and could have just recreated the pictures from the negatives. He is looking for who took his pictures later. (00:37:30 - 00:53:00)
Plot hole: When Rachael/Ruby is attacked by Pluto in the rafters, Cass, being blind, is able to hear her cry out. When she does, Cass calls out to her by saying "Ruby." However it was a couple scenes later when Rachael tells everyone that she is really Ruby. Cass is surprised to hear this. Therefore, not knowing that Rachael was really Ruby, she should have called out "Rachael" instead of "Ruby" when she was attacked because she didn't know the truth by then.
Plot hole: Billy's not tall enough to impale Linnea Quigley on deer antlers.
Suggested correction: The movie blatantly shows Billy lifting her high enough above his head to impale her. It's literally right there in the scene. Additionally Linnea Quigley talks about the making of the scene in the documentary "In Search of Darkness Part II," and talks about the actor living her high above his head over and over while making the scene.
