That being said, most of this movie is pretty spot on. Even some of the dialogue is taken from the book. It's dark and gritty. The humor is mostly at the expense of others. The violence isn't really gratuitous (as some critics have accused) so much as it's to the point. Porter isn't there to monologue or impress. He's here to get his money, and that's it. He has no time for flashy shows of sentiment. He's all business all the time, even when it means killing fellow bad guys (face it, Porter is a bad guy). There was also a director's cut done that moves some things around, cuts out Kris Kristofferson, and changes the ending. Both are good and worth a viewing.
