Michael Clayton was great. With a fantastic script and cast, there wasn't any need to resort to action to keep things suspenseful or tense. The opening monologue was particularly cool and a great way to start the movie.
Great story, acting, cinematography and music, but the ending feels a little bit too toothless, and gives movie a bland message. I was expecting a cynical, cold ending, that's not what I got. Other than that, it's really good.
Surprisingly, quite good piece of cinema.
