This movie is just about as bad as one would expect it to be. Actually, it’s even worse than one would expect it to be—and more horrendous than the two previous Big Momma movies, something I didn’t think was possible. Martin Lawrence returns as Malcolm, the FBI agent who goes undercover as Big Momma, the obese alter ego that is so obviously somebody wearing a fat suit. Lawrence, of course, returns to his worn-out shtick of talking really wheezy while pretending he’s an old Southern woman in a muumuu. The twist this time out is that Malcolm’s son, Trent (Brandon T. Jackson, a long way from his Tropic Thunder glory days), witnesses a murder, and must now dress as a woman, too. Malcolm and Trent wind up going undercover and chasing evidence at an all-girls art school, where Big Momma becomes the house mother. So you basically get Bosom Buddies without the comic genius that was Tom Hanks and Peter Scolari.
