Mr. Troop Mom won't win awards for breaking new ground in plot surprises. There's a rebellious daughter, a clique of "mean girls," an over-the-top drill sergeant of a camp director, and a make-or-break competition that requires the girls to overcome their differences and work together. The Serrano family dynamics include a manipulative daughter, a wholly inattentive dad, and a babysitter (Elizabeth Thai) ready to amp up any conflict that arises, and it's all chalked up to the missing maternal influence.
But as family fare goes, this is a decent film, with its message of figuring out the right problems to solve and finding ways to be family. Lopez is good as the hapless dad, but his funniest moments come when he is allowed to riff, as he does on his supposed love of camping. For all her rebelliousness, Naomi is a decent kid who has surrounded herself with a supportive group of friends. And while Jane Lynch nearly pops a vein as Ms. Hulka, the militaristic camp director, there's no one else who could have played the role as memorably.
