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?
At one point in time I would've liked to see a followup to Quantum Leap, or even Sliders, just to resolve the cliffhanger endings. But too much time has passed now. Given Hollywood's track record with continuing old shows decades later (X-Files, I'm looking at you) I'd rather they just pass on it.
