That's your opinion, not fact.
Obviously, you're not a fan of the show. Fine. It wasn't your cup of tea.
In MY opinion this show is rightly considered an iconic show. Of the 156 episodes made, there are 152 that I would say meet the standard of excellence in my eyes. That is a GREAT track record for me.
There are only 4 that I say I would not watch a second time....MR. DINGLE THE STRONG, THE LONELY, THE MIRROR and WHAT'S IN THE BOX.
The rest I can watch over and over again. So the show is far from 'crap' as you put it, in my view.
What's wrong with The Lonely?
Well, I wouldn't say there's anything REALLY wrong with it, just a depressing story with a depressing ending. I can't really bring myself to watch it another time.
Plus Ted Knight's character was so obnoxious that I wanted to kick him all the way to Anthony's cornfield, or save a place for him on the Kanamit's spaceship.
Perplexed that you put The Lonely on your list. Wonderful episode. Music by Bernard Herrmann is magical.
As I said it had nothing to do with the quality of the episode....it's just not an episode I want to revisit.
