MASH was mentioned, but as a good or bad series. Seems to me, statrted out "good" wuitth the movie boost in everyone's mind, ended up awful, with the smugness of certain characters.....
Babylon 5 was, I thought, exceptionally well done for a TV series, including the writing. As was FARSCAPE , WITH A FEW crappy shows, but, hell, who's perfect?
X-Filse, ran hot and cold, but I laughed a lot with the Charles Nelson Reilly show....they knew not to take themselves too sereously.
And then there's Quantum Leap, one of the better shows, and I enjoyed the waythey poked fun at themselves too.
As for the Olden Days, Mary Tyler Moore, awful, Gilligan's Island, crap, but nice chick, that Dawn, wasn't she? Eight is Enough, "hated it!", Same My Three Sons, The Brady Bunch, would send me screaming from the room.
Seinfeld bored me, so I don't think I ever sat thru a complete "episode". And there were plenty WORSE that I've blocked from my memory almost completely, a couple with Pam Anderson, I think, and many many more thtat figure in trivia games.]
The good thing about horrid TV is that I read a WHOLE lot of books over the years....
