The entire time I was watching Black Swan, I was thinking about Catherine Deneuve in Repulsion and in a smaller way Tom Courtnay and Albert Finney in The Dresser. The film is definitely flawed in many ways, but the manifestation of the character's mental problems and their parallels with her performance are fascinating and terrifying. Portman and Kunis play the ying and yang to perfection. Cassel is brilliant, as always and Hershey is perfect as the domineering mother. While I think it played out perfectly, some may not like the violence in the sexuality of the movie and others my grow tired of the endless dance sequences, but they both are integral in the story telling. Another beautifully filmed story by Aronofsky.
