Birdman owes a lot to this film
I'd even go as far as saying that had Black Swan not been such a roaring critical success back in 2010/11, Birdman would not have done as well. It made a film like this, with largely surreal elements, accessible to mainstream audiences.
I'd also like to comment on Black Swan's recent backlash. I'd attribute a lot of this to the fact that it's a female driven film, and that male audiences like to demean films that revolve largely around female characters. Had the centre character been a male, IMDB would be hailing it the greatest film of the 21st century. You only need to look at the Top 250 to see how testosterone-laden the tastes of film goers on this website is.
I'm looking at you, man-children voters who haven't grown out of their adolescence and are still obsessing over mindless escapist garbage Superhero flicks that have been done to death. Black Swan is a seriously dark art film, that recalls the work of greats like Polanski, Lynch and Cronenberg. It is brilliantly acted and beautifully told with utterly breathtaking cinematography.
