The sight gags in this one are even funnier than in the first. The Bo Derek beach scene had the audience rolling in the aisles. And that was just one of many. I especially liked the friendship that developed between Big Momma and the mother of the family she nannies for. Did anyone notice the mom's southern accent? It was a refreshing change from the humor that is usually milked from between outspoken black females and prissy white females. Good for you, Big Momma.
But Big Momma still does some funny ragging on white culture, as well as just yuppie culture of all colors. I don't agree at all with the poster who wondered why Martin Lawrence tries to portray an action hero. Personally, I thought Martin looked extremely fit in this film and found his stunt work and role as an FBI agent very believable. I found it to be a definite positive for the film as a whole.
Nia Long is feisty and as funny as she's allowed to be. On screen she and Lawrence work well together. The kids in this film are very, very good. Even the dog is funny. It's more of a feel-good movie than the first one and as a mom who plans to now take her kids, that's fine with me.
The bottom line: Lots of laughs if you're the kind of viewer who enjoys screwball comedies that aren't artsy and if you enjoy humor that plays upon cultural differences and experiences. Personally, I love Big Momma and would welcome her at my family reunion any time.
