I think that Stone's political movies are the best ones he makes. Even if I don't agree with the message, I am always amazed at how well the film is put together. I'm a big fan of "JFK". By all rights, it should have been a dull film. No real action, lots of interviews and research and an occasional court room yelling match, but I think it's absolutely beautiful and fast paced.
"Nixon" was a pretty good show too. I saw it for the first time recently, and was surprised that Stone didn't paint him as a cruel and sadistic devil (which is what I had expected from an Oliver Stone/Nixon film)
I hope "W" is at the very least an interesting flick.
