Alright, so I just watched the original 'Black Swan'.
Every single thing I wrote in my review about 'Black Swan' is much better and absolutely stronger in this film.
The concept of an identity crisis in this film is 'alive and kicking' in a flashy way and as a result of it being done so well, it lifts the film to such a high level that it is at, The pace with which the film progresses adds to the atmosphere and the lack of knowledge and anticipation as the film progresses, All these things make this film an outstanding thriller that also raises questions about its viewers as well.
