It doesn't mean the show itself is bad, it can be a highly regarded, award-winning gem, but for whatever the reason you can't watch it anymore. For me, it's M*A*S*H. I loved it in its intitial run and would never miss it. Now, I just can't bring myself to watch it. Not sure why. Maybe its subject of war depresses me a bit these days more so than when I was much younger. I know the finale really pulled me down and perhaps that has put me in a funk on the whole series. What shows did you once loved but can't watch anymore?
