Continuity mistake: During the fight between the deadite woman and Kelly in Ash's trailer, the deadite's fingernails change from long to short in one shot.
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.
Continuity mistake: Throughout the entire first season, Ash's 1973 Olds Delta 88 variably has 4 working taillights and then only 3 working taillights from one scene to the next (and even from one shot to the next).
Answer: Series creator Sam Raimi has said that there are three new ideas to continue the franchise, but there's no other information available at this time. Crowd funding could possibly fund another film, sure. But it's such a well-known franchise that it likely wouldn't be necessary. All we really know for sure is that the series "Ash VS Evil Dead" can't return, as it is under partial ownership by Starz, and producer Robert Tapert stated in a Q&A that they weren't interested in selling off the rights to the series. So if more "Evil Dead" is made, it likely wouldn't be a direct continuation of the series.
