A fairly typical buddy cop comedy, but it's enjoyable and has plenty of laughs. Sandra Bullock plays a straight-laced, unlikable FBI agent who comes to Boston for a major drug investigation and pairs up with antagonistic tough gal police detective Melissa McCarthy. The value of a film like this lies entirely with the leads, and Bullock and McCarthy both deliver. Bullock is a talented comedian who almost never gets to show it in a watchable film. McCarthy, fresh off her hit Identity Thief, proves once again to be a talented physical comedienne (as does Bullock, actually), but what should never go unmentioned when talking about her is that she's a wonderful ad-libber. Almost everything she says is hilarious. The rest of the cast is fine, and the film in particular shines whenever they go to the well of McCarthy's loud-mouth Irish family (which includes Jane Curtin), who have a black velvet painting of Jesus hitting a home run at Fenway Park on their kitchen wall. The plot is, of course, rote, and it's probably not a film I'll be thinking about an hour after I've seen it, but it provided a pretty good time at the movies.
