The most striking thing about Darren Aronofsky’s debut feature, Pi, was not its sci-fi-for-mathematicians gimmick, but its aesthetic. Here was a low-budget filmmaker who gave the impression that not only did he not want millions of dollars from Uncle Weinstein, but he had no use for production values. As I write this, he’s just been tapped by Warner Bros. for the Batman franchise, but never mind. His first feature showed a dedication to the celluloid image that made me eager to see what his next step would be.
