The only choice for Tammy is a road trip with her grandmother, Pearl, who has a car, cash and an itch to see Niagara Falls. It's not the escape Tammy had in mind, but it may be what she needs.
It's a rambling, pointless and labored attempt to cash in on Ms. McCarthy's fan base without respect for any audience with a collective IQ of 10. And it's about as funny as a liver transplant.
A lot of good actors are wasted in this film in bit roles, including Allison Janney, Sandra Oh, and Dan Aykroyd. The ones with bigger roles, like Mark Duplass and Kathy Bates, are wasted, too.
Tammy is an object lesson in the art of directing, which is all it would have taken to turn this near-miss into an instant classic. Though that may be true of most mediocre movies.
