Since the entire horror genre is now flush with "found-footage" style stories, I suppose it would have been silly to think that a Blair Witch sequel would stick to the ambiguity and slow buildup of tension of the original. Part of the joy of the original Blair Witch Project was the ambiguity of its ending. You weren't really meant to know if anything seen on the film was truly supernatural or not. Since that's not really an option in the sequel, instead we get a movie that tries to quickly get to all of the supernatural scares and completely undercutting any spooky tension of the original. You also see a lot more blood (the original is practically bloodless) and even
glimpses of some sort of humanoid creature chasing after our protagonists. It really adds nothing to the genre or to the Blair Witch series itself.
Perhaps the only thing it shares with the original is the nauseatingly shaky camera work. Make sure to take a Dramamine before seeing it.
