Consider this title a form of honesty: A movie named after one of the universally annoying whines of childhood isn’t even trying to hide the fact that watching it is a grind for parents. Ice Cube, exploring new dimensions of selling out, plays a committed bachelor who gets stuck on a road trip with his latest target’s two brats. It’s a children’s movie with no wit, no visual delights and no respect for the appreciative abilities of its young audience.
