Have you ever gone back and watched a TV show you used to love, but now it seems ... meh? Northern Exposure. I used to love that show. But now, not so much.
Do NOT go back and watch shows from your childhood that you liked. I foolishly watched an episode of the A-Team and it really ruined my fond memories of that show. So I'm not going to watch the others: Dukes of Hazzard, Greatest American Hero, Transformers, GI Joe, Star Trek: TNG, etc.
