Darren Aronofsky is the absolute best director for any stories about obsession. He's able to get inside the minds of the obsessed and turn it inside out so we can see it. Black Swan is my favorite of his to date. It features an absolutely breathtaking performance by Natalie Portman and some of the most beautiful and terrifying imagery Aronofsky's ever produced. Amazing, stunning, horrifying... one of my favorites of the year. 4.5 stars.
