If you like BBC lighthearted mysteries, old Miss Marple movies, clever whodunnits, etc, forget this movie. Narration over many scenes, almost all the action recast as flashback, detective is a funny part but Craig couldn't pull it off--totally miscast, Main character vomits a lot. I got the feeling the writer imagined it totally differently. If you are doing a lot of vomit scenes for comedy, then really it was supposed to be over the top humour. I've seen dozens of fun clever movies much better than this one. I mean, even sort of weak TV shows with funny detectives solving crimes have better scripts. All the great actors are not well used and don't give good performances, so maybe that's the director who is responsible for that.
