iam going to go against the grain here and say i was thoroughly dissapointed with this film. dont get me wrong, i think dicaprios performance was tits...but having been through heroin addiction (and also having read carrol's book), there are a couple of things that get to me about this film.
1)quite simply, this film (and book, to a lesser extent) is packed with tired cliches. jim is saved by the noble black man...the overall diary entry mood...jim is seen in a seedy bar watching neurtron in the all-star game, the message of "if you use drugs you will end up on the streets selling your body" etc, etc. everything occurs in a short, haphazard, unstructured manner. there is no patience.
2) we are led through jims harrowing descent into addiction and eventually hell (again, superb acting). but what about his recovery and eventual redemption? this part is a breeze through, yet it should be one of the most important parts of the film, IMO.
3) poor character development...lorraine braccos portrayal of jims mother is emotionally charged, yet she serves as a one-dimensional character...her only rapport with jim being one of "tough love".
4)overall, the film is taken far too literally from the book. much of the poetic feel and eroticism of the novel is lost. the film also fails to recognize jims use of heroin as a huge part of his rejection of catholicism.
