I've wanted to watch it for a while, just never did because I'm not a horror fan. I don't think I've ever seen a horror movie that I really like. There are a couple I enjoyed, but none that I have any desire to see again. Oldboy is one of the more popular foreign films that we sell at work.. along with The Host, Pan's Labyrinth, and Amelie.
Amelie = the shit. It's my favorite movie of all time. You have to watch it.
