Star Trek. I mean, for certain values of "astonishingly".
Star Trek gave us a few excellent episodes. I don't think any of the series have been excellent overall, although I'm probably in the minority opinion in that.
I think that's probably a majority opinion. Star Trek's reach always exceeded its grasp. There are excellent episodes and very good seasons (mostly of TNG and DS9) but I don't think I know anyone who'd go to the mat for any of them as consistently excellent.
Simpsons, at least the first several seasons.
Scrubs.
Frasier
Didn't Frasier have a laugh track? I can't watch anything with a laugh track.
Yes. I tried watching it after moving to Seattle (cliché, I know), but couldn't bear it because of the laugh track.
Granted, but it was still a very good TV show. Actually liked it better than Cheers.
