This is actually a review from someone who read the novel before watching, and since I'm sure anyone interested in this movie have had watched or read Choke novel or Fight Club, I won't make a synopsis of the film.
I'm going to start with the cons: I gave this movie a 7 out of 10 mainly because of its cinematography; there was zero creativity involved in it. From start to finish, you never get to see and let alone appreciate the surroundings in which the characters are. With this lack of creativeness, it seemed like the environment from every scene was a cheap set and not actual places. There's no introduction to the city in which Victor (the protagonist) lives, his work, the "mental facility", etc.
This leaves the movie with full of dullness and no life to it, switching from one scene to the next with just the actors interacting with one another with no pleasant detail to it. Some scenes could have been better OR longer (for example; the first choke scene in the restaurant), although nice, it seemed pretty rushed. And talking about longer scenes comes my third con: its length. This movie is almost 1hr and half and I'm sure if they made it at least 2hrs long it could have been better, but that's just my opinion.
The jokes are pretty faithful to the novel and most of them will at least manage to get a chuckle out of you. The protagonist sometimes narrate some scenes a la Fight Club which is a nice touch. The acting is very good and Sam Rockwell perfectly portrayed Victor Mancini as the reckless sex addict. Brad William Henke (Denny) seemed out of place in this movie, since his true character should have been skinny instead of tall and bulked. Same thing with Victor's mom Ida Mancini (Anjelica Huston) which they portrayed her kind of healthy instead of a sick, skinny woman.
Finally, the movie is very good and entertaining with its dark humor, but it seriously lack in the cinematography and length department.
