Martin Lawrence is often trusty in the world of comedy. Maybe I'm just overcoming his awful "Blue Streak," but I felt this comedy--though saggy at times--was quite funny. The premise is undoubtedly implausible. How's a whole neighborhood going to believe that this undercover cop with a latex body that looks somewhat like Big Momma is actually Big Momma? There's a lot of disbelief to suspend. But the gags often worked and I can say I laughed about 75 percent of the time. Some are predictable, like when Big Momma takes a karate class and starts beating the teacher--played by Anthony Anderson--to a pulp, but they still work due to the way they're handled. And Lawrence turns in yet another fine comic performance, with a script that could've used a rewrite but was nowhere near as bad as the crackerjack script he had to work with in "Blue Streak." The talented comic helps keep the movie togehter, with a little assistance from the supporting cast. Paul Giamatti, who was great as Pig Vomit in the acclaimed "Private Parts," is funny as Lawrence's partner. We also have "Me Myself and Irene's" Anthony Anderson and Cedric the Entertainer.
The plot is chaotic, sometimes predictable, and becomes more and more implausible by the minute but the comedy works and because of that we're able to excuse the script's shortcomings. "Big Momma" doesn't deliver the biggest laughs, but it's good, fun entertainment on a lonely weekday afternoon.
My score: 7 (out of 10)
