Written by Melissa McCarthy and her husband Ben Falcone, and directed by Falcone in his debut behind the camera, this features McCarthy as central character Tammy, whose life goes into meltdown and inspires her to go on a road trip with her alcoholic grandmother, played by Susan Sarandon. I think McCarthy is a great actor, but her balls out improvised approach to comedy is wayward from the start here, as she tries to set up the whole initial premise almost in one breath – we watch as Tammy quickly loses her job, her marriage and her head in the space of a couple of hours, setting her up as the traditional comedy screwup that we will nevertheless feel sorry for and root for. Unfortunately, it all has a nervous, awkward and amateurish quality to it, and it never really manages to be funny, with obvious and inevitable jibes at the protagonist’s expense, brief treatment of alcoholism, and a traditional, predictable and largely pointless outcome.
