Crow does have a point. Nothing wrong at all with old people ~~ we luv 'em! But old people playing characters whom you first met when they were young and in their prime can be a grounding experience for many. Yes, 30, 40 years really HAVE passed ~~ for them, and for us. Often a bittersweet experience.

On the flip side, STAR TREK and DOCTOR WHO have recently proven it can work, so bring it on!
