I'd skip the book too.

mild spoilers:

This is not how you make a good movie and here is why. First off the protagonist is hard to get into, is he a punk or appreciative of the fine arts, is he a bicycle man or a driver, is he a hard ass or a lover? The story telling could not decide, there was evidence for everything. There is no way a broad audience can root for a scrawny, talent free nobody who's sense of humor is defined by holding a dead rat to his sister's face. The second big mistake, two thirds into the movie a main character dies. That's like eating a meal and half-way throu... lees de rest.
