Oh, sigh. The last thing anybody needed was a sequel to Big Momma's House. Sadly, Lawrence (Rebound, Bad Boys II) has a lot of fans, and they all went to see the original. So somebody deduced that a sequel would be a good thing. For fans of the original, the sequel will give them more of what they loved. For people who hated the original, the sequel will give them more of what they hated. Big Momma's House 2 doesn't do anything to advance or expand the story, it is just the same story with a few different characters. In other words, an easy way to make a quick buck.
Some time has passed since the original (but not enough) and Malcolm Turner (Lawrence) now works a desk job. His wife Sherry Pierce (Nia Long, Alfie, Are We There Yet?) likes this, since they have a baby on the way and he won't be in any type of danger. When Lawrence's mentor dies, he decides that he is the only person capable of tracking down the killer. He goes back undercover as Big Momma despite the fact that equally capable FBI agents are already on the job. In no time, he has manipulated his way into the Fuller household as the nanny. Tom Fuller (Mark Moses, Monster-in-Law, After the Sunset) works for a large software corporation suspected of creating a program to hack into all national agencies. He is also a suspect in the murder.
The story gets a bit convoluted here. Director John Whitesell (Malibu's Most Wanted, See Spot Run) and writer Don Rhymer (The Honeymooners, Agent Cody Banks 2: Destination London) forget about the murder. Instead, Turner focuses on hunting down this program. The entire script consists of Lawrence walking around in the fat suit and falsetto voice, doing c-r-a-z-y things to his lily-white Orange County host family. The story this time forgoes some of the more risque humor in favor of a family friendly atmosphere. In other words, Big Momma is here to solve a crime and fix a broken family.
Fuller spends too much time at work. His wife Leah (Emily Procter, The Big Tease, Guinevere) is too controlling. She's also often away, but the script never explains what she's doing. Eldest daughter Molly (Kat Dennings, The 40 Year-Old Virgin, Raise Your Voice) is in full rebellion. Middle child Carrie (Chloe Moretz, The Amityville Horror) doesn't have that many friends and needs help with her cheerleading routine. Youngest child Andrew (Preston and Trevor Shores) doesn't speak and has a habit of doing faceplants from high places. Big Momma's House 2 all boils down to how one feels about Lawrence's style of humor. For a lot of people (including this reviewer), his humor is moronic and stupid. The joke is that Turner looks like a large black woman, but he doesn't. It's too difficult suspending disbelief when viewers want to reach out and slap the Fullers for not seeing something so obvious.
