Oh gee, wow, where do I begin with this?
I've seen this twice; once online, and today in the cinema. I can't even put into words how...interesting this film is.
The story, in a nutshell, is a girl; a girl treated somewhat as a perpetual child by her mother, a girl in the New York City Ballet, striving to be "perfect" and portray the black swan. As her mental state deteriorates, we see her become, ultimately, the black swan...a girl who's no longer a child (one must keep reminding themselves that this girl, Nina, is actually in her mid-twenties...yet the whole atmosphere of the film makes you believe she's much younger; thus we see her as a teenager rebelling, in a way.)
I must mention the directing. Based on this film, Darren Aronofsky is pure genius; the hidden 'bits' throughout the film, the suspense, the colours.
The acting was fantastic; Natalie Portman, Vincent Cassel and Mila Kunis were all very impressive. There is no wonder why Natalie won an award for best actress at the Golden Globes!
Overall, Black Swan is a beautiful film, focusing on insanity and the road down to it, beauty, people, dreams and, of course, ballet; the beauty and the perfectionism, how we are always striving for more and what this does to us.
