Good, but where's the story?
This film is severely underdeveloped. Thematically, I understand there isn't supposed to be some kind of startling revelation that completely takes the audience by surprise. The well placed reference to The Great Gatsby hints at the film's inherent symbolism: we are supposed to know exactly how the film is going to end, and that's what ultimately makes it tragic.
My problem is with the character development. There are some really great performances here, but where is it all leading to? I can't find a single story arch in the entire film worth mentioning. I might have completely read the scene wrong, but from what I remember, it's subtly indicated that Mick is - more or less - a repressed homosexual. He's by himself in the dorm room, sniffing Charlie's clothes soon after he arrives. Also, during the weekend getaway, he says something to the effect of, "Polo is gay." His delivery is forced, and it hints at the insecurities below the surface of his alpha male persona. Why isn't stuff like this elaborated on further in the story?
By the end of the film, I didn't really care one way or another about these characters. It just felt like a succession of well-acted scenes that had no particular intent or direction of where they were supposed to go.
