As usual part two is less than part one - sequels seldom reach the level of the original. But when Lawrence dresses as Big Momma it's easy to believe he is a large black woman who is determined to get her way and do the right thing.
This time he plays Big Momma to get inside of the house of a manufacturer who is planning to sell critical data affecting the secrets of the US government. He finds the three kids in the family are just too appealing for him to ignore. Momma 2 becomes Mrs. Doubtfire "2". With far less FBI action we see Lawrence's Agent Malcolm Turner dealing with a dysfunctional family a-la "The Nanny" far more than getting the bad guys. That's OK but probably not what the audience expects.
He has moments of battle which surprise the bad guys, encourages cheerleaders and refuses to remove the bra of a model in a spa locker room where he receives a hot rock massage.
Not great, not bad it's just an OK visit to Big Momma's House.
