Of the top of my head, I can only think of the live-action Punky Brewster show in the 80's. It was on the air when I was a kid, and loved it. Would very much like to see it have a reunion of some kind.
Anyone else have their own wanted-reunions from these times?
Parker Lewis Can't Lose. I loved that show during its original run, though I admit when I watched episodes in the last few years it didn't interest me as much. Still, it had a young cast that has probably changed a lot over the years and it'd be interesting to see them together again.
