Things that sucked:
- That Gene Coon couldn't stay with the show.
- That NBC gave Season 3 a shitty timeslot and Roddenberry didn't care anymore.
- That demographics hadn't come into broader use earlier.
- That if all of the above had been different than S3 as a whole could have been better and
maybe we might even have had a Season 4.
- That they didn't have more time and money for higher calibre f/x (even for the time).
- That we didn't get to a bit more variety in Starfleet designs.
- That we didn't get to see more of the
Enterpise's interior.
- That Uhura, Sulu, Rand, Chekov and Chapel could have gotten at least one episode each with more to do (or perhaps something like a TOS version of TNG's "Lower Decks").
- That we didn't get to see one female starship or starbase commander to finally put the Janice Lester argument to rest.
