Eversharpe: Babylon 5 & Quantum Leap
It's been a long time since I've seen either.
If you have VISION TV through your cable/satellite provider, Quantum Leap is on every Tuesday.
For me, the shows I'd like to see on the air again are:
Incredible Hulk
Night Stalker (original series)
As for non sci-fi shows I'd like to see again, those would be:
Hogan's Heroes (used to be on TV Land or Deja Vu but haven't seen it on either for a while)
Run for Your Life
As for first run shows I'd like to both "Monk" and "Ashes to Ashes" on the cable channels I subscribe to (maybe the latter will air on Showcase soon).
