So most of the shows I loved in childhood or young adulthood aren't on the list, unless they are shows I'd still consider good.
There are many aspects to "good". In my example, Mork & MIndy. It isn't what I would consider a "good" show based on production, acting, etc. But it is still "good" as it still cracks me up and is still exactly what it was. A perfect vehicle for Robin Williams to do him. The show isn't going to win any awards but it is still one of my favorite shows.
For sure, and I liked what somebody else posted about being rewatchable now as well. IMO a great comp is the talk in the 80s thread, and that is the list I struggled the most with. A nostalgia pick for me that is bad now (IMO) is stuff like Police Academy 2-4 or Screwballs or Mac & Me. A nostalgia pick that is still good is Ghostbusters and Karate Kid.
As I was watching a few things while thinking, too much of my list was in the first category. Part of that is that in general I'm not as much a TV fan as other stuff, but I was surprised how little I enjoyed or was laughing with some of the shows I tried over the past week.
Also, TBH I didn't want to have to think about which version of Scooby-Doo or TMNT I had to list, for example.
