I was interested until I saw the trailer. Either the movie is bad or the people doing the trailer had no clue. I don't like movies that are too literal or go over the top (unless on purpose ), so the moment she started sprouting little barbs/feathers didn't go well for me. And in general the scenes in the trailer seem like bad over-acting of an even worse script, hopefully they only look like that because they're taken out of context. But then again the movie may just be an overambitious pseudo-psychodrama, kind of crazy, crap. What exactly is it trying to be anyway?
As for Aronofsky. The only of his movies I've seen to the end was The Wrestler, and I didn't like it that much. Much ado about nothing. I remember asking after the final scene, "That's it?" So we think we're going to live forever when we're young, we make mistakes, some big ones, we're trying to fix them and it's not always working, second chances might not work out and then we die. That's how it came off to me, like one of those yellow cheat books that will summarize a great book for you without even trying to go to any depth about it, and with none of the brilliance of the original.
I remember watching Pi but I don't know if I finished it, it was a long time ago. I found it kind of interesting and kind of boring at the same time. Or maybe rather too monotone. Requiem of a Dream was so overindulgent and already proclaimed by many to be the cinematic second coming of Christ, that I didn't have much patience for that.
