Watched this on Prime. Definitely stupid, but pretty funny and enjoyable. Basically Scream x Hot Tub Time Machine. I'm not a huge horror/slasher movie guy, which is probably why I liked it. I don't think fans of the genre that enjoy being scared would like it, but if you're tepid about these kinds of movies like me, or if you prefer the humor/horror mix like I do (i.e., Cabin in the Woods) then I think you might have a good time.
