Federal agent Malcolm Turner (Lawrence) and stepson Trent (Jackson) head to an all-girls performing arts school to search for evidence of a murder.
“You never know when Big Momma might show up again,” warned Martin Lawrence at the end of Big Momma’s House 2 and he’s carried out the threat. After his teenaged stepson Trent (Brandon T Jackson) witnesses a murder, FBI agent Malcolm (Lawrence) takes him undercover at an all-girl school for the arts. There, they search for a flash drive whose location will be obvious to audiences. Both must don frocks: Malcolm in his Big Momma disguise, Trent as a female student. To be fair, both drag up well, but the story’s as inane and low on laughs as its predecessors (main joke: a boy dressed as a girl fancies girls). This also spends an inordinately long time on bland musical numbers - trying to Glee-up Big Momma ain’t gonna fly, child.
Whoever demanded a third instalment of Lawrence's mirthless mash-up of weak gags and cross-dressing horrors should be imprisoned and forced to watch it on repeat until they repent. Avoid.
