It is always a tall order to translate a classic book into a film and I was fully prepared to detest this one. I was definitely one of those who pronounced this 'unfilmable'.
However,I was pleasantly surprised by both by the treatment of the story and the actors. I wasn't at all convinced that Kristen Stewart would make a good Marylou but I have to say she won me over.
There's not a lot to say about the story ... it's a road trip, there is lots of introspection and writing and copious amounts of sex and drugs. The actors turn in very compelling performances and the film is beautifully shot.
For me, the book in this case is king, but the film is still worth watching.
