Graceful, clever (even if I think that the "past" part of the film could have been clearer and more useful to the plot).
Some shots are very ingenious, some are true pieces of work, and the 3 periods are linked with beautiful continuities. This director definitely knows what is cinematography !
I discovered Darren Aronofsky with Black Swann, and wanted to watch his other movies. I'm far from disappointed, but I would have liked to be even more surprised (with the story and the way he tells it) !
