In director Darren Aronofsky's Black Swan, the first words we hear are uttered by professional ballet dancer Nina Sayers (Natalie Portman), who tells her mother, "I had the craziest dream last night." And for the next 105 minutes, the movie unfurls like a crazy dream itself - a crazy, fascinating, terrifying, exhilarating dream that you have no desire to wake from. You can label the film a psychological drama, or a hallucinogenic thriller, or an art-house horror flick, and each would be appropriate. But none of those tags really hints at how much delectable fun Black Swan is. As with a dream that you want to return to the moment you wake up, you want to experience the intoxicating, rapturous weirdness of Aronofsky's vision all over again the minute the end credits start to roll.
