Black Swan is one of Natalie Portman's greatest achievements in the movie industry, which landed her a golden globe for best actress. It's rated a hard R for good reasons. The movie has an intense, dark and unsettling atmosphere throughout, in which the main character Nina is suffering from rather severe psychological problems, experiencing bizarre yet disturbing hallucinations and being the victim of getting persuaded and controlled by other characters, inluding her demanding mother. It reminds you of the mental disorder known as Schizophrenia. The plot is about Swan Lake, one of the best ballet productions in the world, and Nina is shown being driven to the point where she's determined to obtain the position of the Swan Queen, including the stressful and psychological challenges she had to endure (manipulated and abused by her mother and her own ballet instructor; graphic self-mutilation; and accused by others as the reason how Beth lost her position). The violence is more disturbing and hard to watch than most r-rated violence, such as Nina peeling a hangnail, stabbing another woman with a shard of glass, picking at a bleeding red rash on her upper shoulder, having bloody cracked toenails from extensive use of her feet during ballet training, and hallucinations of transforming into the black swan (the darker, more sinister side of her), which can be very frightening at times. Language is infrequent but strong, uses of f**k (often sexually), sh*t, and a use of c**k vulgarly towards a woman. There are some intense sexually charged scenes which includes two women performing oral sex on another, self masturbation, and Nina making out with random strangers while high on esctasy at a club. This movie is a masterpiece, showing the evolution and downfall of the Black Swan, yet the violent disturbing content, frightening hallucinations, and the intense, dark atmosphere will be too much for younger viewers.
