John de Lancie is the only ST:TNG cast member I've seen, and it was at the only Convention I ever attended. His behavior was a lot like Q, and I was really turned off by the way he acted.

Levar has come a long way from the days of Kunta Kinte! I think he's a great actor and I wish he was in more movies. And sometimes I just like to watch Reading Rainbow... merely to hear his voice. LOL
