Nixon looked ridiculous, but the actor was all right. I loved the opening scsene, where it basically showed hwat had happened up until the movie started. And some good old Dylan doesn't hurt either.
Also, Jimi Hendrix. That's about all I have to say for the movie; not really into long reviews. It was satisfying, but it dragged on a bit. Understandably so; remember they're cramming for most people 6 or so hours of reading into about 2 hours 40 minutes.
