Disappointed
Don't get me wrong, I think the starring gentlemen were wonderful but everything else was awful. It's obvious the director tried to create an artsy feeling, but the question remains: why?
The most ridiculous moment was the one, when they are walking away from the helicopter in slow motion and there's some bad rap music playing on the background. This simply doesn't belong in a film that's supposed to be taken seriously.
The other thing is the camera... Someone should tell this guy that he isn't directing a Von Trier movie but a documentary.
What might be the most ANNOYING fault however, is the fact how their debates were cut. As soons as one of them finishes a good argument and the other begins to respond, it all cuts away. I realize you can't have the whole 2 hour debates in a movie, but you could still use your brains until you come up a plan, how you're going to cut it, without making the whole movie seem amateur.
