"College Road Trip" is Disney's attempt to put Martin Lawrence, usually associated with a more robust brand of comedy, in a family-friendly, G-rated picture. The result is mixed at best. There's a nice pro-education theme struggling to emerge from oceans of clumsy humor here, so let's be generous and say the movie deserves about a C-minus.

Lawrence's co-star is Raven-Symoné, the young veteran of "The Cosby Show" and various Disney ventures, including her starring vehicle "That's So Raven." Her background offers a clue to "College Road Trip": It boils down to a TV episode boosted to feature length, with slapstick and heart-tugging filler - fine for the Disney Channel, but thin stuff in a movie theater.
