None of those episodes were horrible to me. The "Of course not; it's just a game!" ending in Move Along Home was great, Masks and Spock's Brain were cheesy fun, Shades of Grey was just a clip show (something sitcom fans at the time were very used to), and Sub Rosa...came out when I was a teenage boy and thus able to appreciate Gates MacFadden's...performance.
None are likely even in my top 100 (150? 200?) Star trek episodes, but they're fine. I'd certainly watch any of them over Dear Doctor or Author Author or Code of Honor or Threshold or Profit & Lace or Homeward or...
Move Along Home: If this was DS9's worst "growing pains" episode, it held together pretty well.
Masks: This one was pretty good, I thought. Especially Brent Spiner getting to stretch.
Spock's Brain: Ok, pretty dumb. Plus the fact that unless there really was a Cerritos type ship following Kirk around and cleaning up his messes, the women on the planet would be dead for sure.
Shades of Gray: The clips were good. And the episode itself had its moments.
Dear Doctor: An effort to map out why Starfleet needed a prime directive, but miscalculated.
Author Author: Had its moments.
Threshold: Would still have been bad without the salamanders.
Code of Honor: Would still have been bad if the planet dwellers had been white.
Homeward: When not character assassinating Picard, this one's Ok.
I'll take any of the bunch over Half a Life.
