Jaysus, this movie is dark, the title doesn't lie. An intense watch, but great all the same, and even earned Natalie Portman an Oscar for her performance. She stars as a repressed ballet dancer who fervently pursues the lead role in Swan Lake, although the director convinces her she will only be capable of dancing the part if she embraces her darker impulses. And eh yeah, safe to say, she finds her dark side alright. Who knew ballet dancing could get so bat-shit crazy?
