Aimed at a young audience, “Save the Last Dance” teaches valuable lessons about the evils of bigotry and about the need for selfless acts in maintaining relationships. But it’s not aimed at adults. Those who still ride on big yellow buses may enjoy the earnestness of the cast and the athletic dance routines. Older folk, however, may snicker at viewing high schoolers on Hollywood’s version of the road to self-discovery. Then there is that music. Hip Hop. Rap. For many of us who are still listening to Lady Ella or the Chairman of the Board, these rhythmic monologues are little more than annoying expressions of anger and frustration. It is a form of music we hoped would go the way of disco. But it remains, as a new generation desperately seeks harmony. I know, I’m showing my age, but who can listen to Puff Daddy during a candle lit dinner?
