I've seen some bad horror films before. I generally don't watch anything that gets less than a 5.0 (out of 10) rating on IMDb, but if the movie stars an actor I like (like Drew Barrymore), I will take a chance on it. In this case, the 4.4 rating was WAY too generous. I've read a lot about doppelgangers. This movie doesn't have anything to do with any of the legends about them. Do yourself a favor and skip it or, if you want to see Drew, watch all but the last 15 minutes. Trust me, you'll thank me for not putting you through that last segment. It is one of the worst I've ever seen on film, and that's saying a lot.
