Good messages compete with jumbled stories in "Madea's Family Reunion"

Tyler Perry's heart is in the right place, but he still has a tin ear.

The same tonal problems that plagued last year's "Diary of a Mad Black Woman" resurface in "Madea's Family Reunion."

Serving this time as director, besides having written the script and starring in three roles — including, of course, dragging it up as the pistol-packing Aunt Madea — Perry has a message of empowerment and self-respect that's not just important for women to hear, it's essential. He also has a few choice words for the men in the audience: Stand by your women and your families. They need you.

Unfortunately, all that too often gets muddled in his mess of a screenplay. Maybe the material worked better in its original form on stage. But in cinematic form, "Madea's Family Reunion," like its predecessor, jumps jarringly between romance, domestic drama and broad physical comedy. At times it feels as if Perry made three separate films, dumped them in a blender and hit the purée button.

Like Kimberly Elise in Perry's first film, who went from pampered society wife to mad black woman, Rochelle Aytes stars as Lisa, the beautiful, stylish fiancée of a beautiful, stylish Atlanta investment banker. But behind closed doors, Blair Underwood's Carlos repeatedly abuses her, and Lisa's materialistic mother (Lynn Whitfield) only encourages her to withstand the beatings to maintain her comfortable life.

Madea finds time to give her and Lisa's sister, Vanessa (Lisa Arrindell Anderson), no-nonsense advice about their love lives while caring for a wayward foster daughter, sparring with her dirty-old-man older brother (Perry again, in white hair and overalls) and planning the family reunion.

All these elements pop up out of nowhere, with seemingly no attempt at a smooth transition between them. Madea pummels a boy on the school bus who's been bullying her foster daughter, followed by a scene in which Vanessa and her new boyfriend, Frankie (Boris Kodjoe), rhapsodize about what a blessing kids are during a play date at the park.

Later, Vanessa will get on stage at a club during a poetry slam to perform one of her painful original works: "He. Gives. Me. Courage. To love." It's one of many scenes that feel corny through the smothering use of romantic R&B music.

There is one great moment at the family reunion, though, in which Aunt Myrtle (Cicely Tyson) lovingly scolds everyone in attendance for not behaving like better people, for not taking responsibility for themselves and not loving each other steadfastly enough.

It's a rare moment of truth in a movie that too often feels either melodramatic or self-consciously madcap.
