Let’s start with the good news: If you didn’t already know it, Melissa McCarthy is a very very funny lady. Her timing, physicality and improvisational skills rival some of the greats. She and Sandra Bullock make a delightful and refreshing duo. The bad news: Nothing could elevate this hackneyed, recycled, throw-away plot to the level of comedy classic.

Kate Ashburn (Bullock) is a buttoned-up fed on the trail of a drug kingpin. When her search takes her to Boston, she is forced to team up with nitty-gritty detective Mullins (McCarthy) to catch the mystery man. Now, let me stop you right there. If you think for one second that Mullins and Ashburn initially hate each other, but slowly Ashburn’s book smarts and Mullins’ street-savvy combine to make the pair an unbeatable crime solving force and even better friends, well, you’d be, um, correct.

So amid this wildly predictable mess of a plot, there are several almost redeeming moments of comedy. No doubt the studio has Martin-and-Lewis visions for Bullock and McCarthy. Hopefully next time, they will actually give them a movie to accompany their talent. It’s a 6.
