Plot hole: Old Ash travels back in time to 1982 to snatch the Necronomicon before Young Ash ever finds it (which should, presumably, erase all of the evil events from the original Evil Dead film right up to the present). Upon escaping the cabin, Old Ash finds that the timeline has self-corrected, and his amputated right hand has reappeared on his arm. But he is still in the 1980s. If the timeline had truly self-corrected, then Old Ash's car, his friends, and he himself would have vanished instantly from the 1980s, because the purpose of their mission never existed.Charles Austin Miller
Continuity mistake: The Michigan State Police arrive at a rural 2-storey home that has been overrun by Evil. As the police park in front of the darkened house, there is something like a million-candlepower flood light about 30 feet in the air, back-lighting a gnarly tree in the front yard and casting harsh light and shadow across the scene. The police exit their vehicle and, in one camera cut, the brilliant light has moved entirely into the backyard, now back-lighting the house. These can't be explained as yard lights: Upon entering the house, the police discover there is no electrical power on the premises.Charles Austin Miller
Trivia: While the film contains numerous references to "The Evil Dead" and "Evil Dead II: Dead by Dawn", it contains virtually no overt references to the third "Evil Dead" film, "Army of Darkness." This is due to an issue with the rights to the third film, as they are owned by a different company than the series and the first two films.
