Fell asleep during the last 15 minutes of Primer: What if it actually worked? last night. Not because it was boring - far from it - but because I was exhausted.
Man, that is a movie you do not want to miss a single millisecond of for sheer plot comprehension. I'm going to watch the ending when I get home today and then re-watch the movie 1 or 2 more times. One guy I know watched it 8 full times before he completely understood everything that was bugging him about the movie.
