fantastic review.. watched the movie last night and loved it. however, the one thing you didn't mention was the score. Johnny Greenwood (radiohead) did an amazing job of finding the perfect blend of dark and optimistic...often at the same time. his score was spooky and really added to the movie.
Joaquin Phoenix was phenomenal in this movie. he looked terrible, his posture was awful, and in every scene it looked like he was one moment away from a total break (but unclear if it would be into a pool of tears, or run around beating the crap out of people).
the scene of Joaquin and Hoffman in jail was a brilliant way of showing their two personalities. Freddie was kicking and jerking around in the cell, while Hoffman was calmly taking a leak.
