The idea and the title are good - what one could do with such a theme! Unfortunately the execution of the idea is mediocre and superficial. Mr Inaritu bypasses a real opportunity to say something true and deep here. Instead, he stays on stereotypes for the sake of the striking and shocking impression, that is it is shallow. Am I the only one that thinks this film is racist, or better plays with racism as a means of impression? The same that does with sexism etc. A lost opportunity not just to impress but to shake people out of their seats.
