Here it says its a thriller/drama:

Bumping this, after seeing it on DVD for the first time this morning.
I went in expecting the worse, and it was actually a pretty damn good thriller. It was nice to see Stephen Dorff back in a supporting role that meant something.
What I really enjoyed is that the whole premise of the movie was extremely believable, and didn't come off as a "Hollywood" thriller.
That said, just go rent it. You may be surprised!
