A Sad Dean?
First I'd like to say that my post is not designed to criticise the film because I do love it so.
It's just...
It's been a while since I read "On the Road" but I have never forgotten Dean's spirit in the book and remember for the most part he was almost always quite happy regardless of problems he has or the people around him have. The only time I remember in the book that he's upset is when Dean and Sal are having a meal in a restaurant and Sal loses it with Dean after the latter remarks that Sal is damaging his own kidneys; a remote reference but I can't remember another time Dean got upset.
Now, maybe people will post quotes that are long forgotten to me where Dean expresses a sadness (and not one which is brought on by the beauty of what he's seeing or something like that), but in the film it suprised me how he was on the verge of weeping at the end when Remi didn't let him go with Sal to the concert or whatever. In the book I assumed that he didn't really seem to care.
Something has to be done, but nothing too original, because hey, this is Hollywood.
