I watched a few episodes of Captain Nice and Mr. Terrific during the original runs. But they suffered by Captain Nice airing opposite I Dream of Jeannie and Mr. Terrific opposite Rat Patrol. While I enjoyed both I liked the opposition better but lamented that I couldn't watch both. It's shows like that I truly long for on disc so I can see what I was missing. Of course if my favorites weren't on disc I'd want them as well and there are several favorites in the "minor" shows and the "shows with 2 or more seasons" that remain unreleased lists.I've never seen The C.A.T. but it has a stellar reputation and Robert Loggia is a terrific actor so I'd probably sample that if it were given a high quality proper release.
Two other kiddie shows I've never seen - Captain Nice and Mr. Terrific. Are they any good. William Daniels is a favorite of mine and this would seem to be a different role for him.
