Broad and bawdy humor sells this retro paean to old-school patriarchy. James Earl Jones is patriarch Papa Jenkins and Martin Lawrence is his son RJ, who’s not pops enough in the eyes of his 10-year-old son Jamaal (Damani Roberts). By the end of this ensemble romp, fathers and sons bond, a bully falls, sweethearts re-bloom and kin close ranks to expel an interloper. Making it in L.A. for the past nine years, RJ is a talk-show host with the bestseller “Team of Me” on the self-esteem shelves. RJ brings his reality-TV-celeb finance Bianca (Joy Bryant) and his son from an earlier marriage to the fiftieth wedding anniversary of Papa and Mamma Jenkins (Margaret Avery). Bianca learns that “Roscoe” is RJ’s “government name” and that his people are way too country for her city tastes. When he declines some ribs, his brother taunts him: “That black Paris Hilton has sissified you off the pig?” All is reconciled, as symbolized by the hook-up of an L.A. poodle and a backwoods Georgia pooch. Writer/director Malcolm D. Lee (The Best Man, Undercover Brother, Roll Bounce) upholds down-home family values with great energy and zero originality. With Michael Clarke Duncan, Mo’Nique, Cedric the Entertainer and Mike Epps. 114m. (Bill Stamets)
