Hollywood likes its children to be cunning. It often calls on them to bring lovers back together and outwit the vile. A bargain is struck - life will be innocent and delightful if the child can achieve something monumentally adult first. Nancy Meyers's remake of The Parent Trap (U), the 1961 Disney film, does this.
