We'll keep this review short.  You gotta pay unbelievably close attention to this movie to even grasp the concepts.  I got bored about midway and started playing tetris on my cell and then when I finished I was thinking, "wtf!"  Philip Seymour Hoffman was pretty awesome, and the premise of the movie is awesome, but damn it could have had more not so drab moments.  I don't even think I can explain the movie... geez.

Fell asleep: no but others around me did
Overall? strange flick, boring at times
Would I recommend? ouch, probably not
Would I watch it again? sure if I wanna fall asleep!
