my god and ryan gosling have make a lot of deep character in his career and this be one of his wonderful act job . for me this be a very deep movie and need a lot of concentration and not because be difficult to watch and just because you understand it if you put your shoe in this kid and even though have everything and have famous father that be a writer and have a deep mind and you do not understand why he kill this poor kid and until you really hear what he have to say and you start to think and at least to me and that a lot of thing that he say be true . simple kid and sweet and very gentle and in a way normal like any teenage and but inside of him suffer because he start to look at the world in a different way and then you understand why he do what he do . i recommend this movie for those who like deep drama .
