It was creepy/unsettling, but I felt like it was all for nothing. I wouldn't say I hated the movie, in fact I enjoyed quite a bit of it, but parts of it felt cheesy, and as a whole I felt like there wasn't much really going on. I dunno, maybe I need to watch it again, but I doubt that I will.
It was different than what I expected though, so maybe that had something to do with it.
Much different than House or Rejects.
Pretty much exactly how I felt. In my opinion, the best part of the movie was the last 30 min.
