I think Darren Aronofsky is genius.
I usually like his movies, too. Pi, Wrestler, Fountain, all really grand. Requiem I can't get myself to like, naturally, but I admire what it is.
Now, Black Swan is so... I don't know if "clichéd" is still the right word. There's everything in there that you expect a ballet movie to have - every stereotype, every scene you need, every great reveal of psychological drama is predictable, there's really nothing new to, it felt so old and dull, yet tried so hard to use its "twists".
