I guess this movie is a specialized taste, given the discrepancy between my review and the average rating, but I thought it was freaking hysterical, with the advantage of being substantially original.
Ever the optimist, I watch (or at least start to watch) a lot of so-called comedies and, believe me, most of what's called comedy is basically "story that couldn't find a better genre". Which is my way of saying that I appreciate a real comedy. Having said that, this is not your traditional Inspector Clouseau or American Pie sort of comedy --- creating funny situations that usually involve someone looking silly, slapstick, misunderstanding, that sort of thing. It's the harder, and more rarely successful, comedy of the absurd --- a ridiculous situation, where everyone behaves just slightly off-kilter. Much of that sort of thing relies on embarrassment, ie excruciating comedy, and while I like my Sasha Baron-Cohen in small doses, I find that hard to watch.
But this is something completely different. The situation is (and remains) hysterical because our heroine has such ridiculous reactions to everything, starting with her utter lack of concern at coming home to her dead boyfriend. In addition to the absurdity of each successive stage of the story, Mary, the main character, is a marvelous collection of incongruous attributes. She appears to be the embodiment of a dozen comedy stereotypes, but she's not quite any of them. She's utterly self-centered and uninterested in anything that's not to her immediate benefit or interest --- but she's Heather Graham and so, not just pretty but sweet and innocent looking, that you can't really believe her narcissism. She's a slacker and a moocher --- but she does have some real talents. She's irresponsible and short-sighted --- but she is also competent where it matters.
I'd put it in the same sort of category as _Violet & Daisy_, or _Family Weekend_, or _The Big Hit_, three other movies I can think of with ludicrous plots and characters, that all work because they buy into the storyline enough that you care what happens, while simultaneously playing up how insane their story is.
