Obviously this movie isn't popular just by looking at the ratings but I personally didn't find it too bad. I've watched it more than once, which is saying something.
If you like movies with a bit of a twisted plot, then you may just find it interesting. I was somewhat confused to start with but by the end of the movie it made a lot more sense. It's one of those movies where you need to wait until the second half of the movie to start seeing what's going on, and I'm not saying that is a bad thing.
