There are actually a lot of similarities between the main character and myself: cat lover, has a job as a writer, not that neat a person, hard on money... Though I probably would never achieve her level of success (she did get her books published), nor would I do anything criminal.
Anyway, midway into the movie, when they entered her apartment and complained about the smell and flies, I thought for sure her cat was dead...
The movie is superbly acted, by both McCarthy and Grant, and very engaging and I think quite realistic. Sometimes the lives of others, even those who are pretty @sshole-ish, are just fascinating to watch.
