this be an excellent film and but momento ( nolan other big budget film ) be much well . i would recommend people go to see momento and then if they like that and see this film . the film be shoot in black and white which i be a bit annoyed with at first but once into the film you understand black and white be the best way for the film to be see . it be extremely gripping and reasonably easy to understand even though the way it be make be extremely clever . element of the storyline i think be a bit daft but the film be definitely worthy of a second viewing . to conculde the film have a clever plot and clever twist and turn and very good acting and bearing in mind the budget of the film i have to say that it be pretty amazing .
