He wrote a book about making it. The section on studio interference implies that it was all egregious, but it lists Paramount trying to fix most of the problems that were still in the final film.
She directed episodes of both "Enterprise" and Star Trek: Enterprise", which each lasted two seasons. The stealth name change was surprising back then.
There was a spinoff pitched during TOS called Hopeship featuring M'benga. The pitch for NBC/RCA was that instead of introducing expensive colorful sets, they could stay shipboard and have expensive alien makeup and costumes.
A Quality of Mercy also showed Una in prison, and Those Old Scientists implied she's revered. Did sending that letter prevent Pike from recruiting her lawyer? Things are already not heading down the exact timeline we saw Ortegas alive in.
Boimler is prone to exaggerating and has strange perspectives. It could be some obscure holiday on a planet he saved, or a Starfleet tradition to commemorate just on ships named Enterprise. Or there's another major holiday which coincides with Pike's birthday.
He reacted as if it was an actual Federation holiday, which would be stronger evidence if he wasn't already terrified he'd altered time.
And the TOS theme does have lyrics, though they're terrible and Roddenberry just wrote them to unapologetically steal half of Courage's royalties.
Ilia's theme from TMP also had lyrics.
The new producer took over for season 2. Season 3 is clearly what he imagined 30 years after All Good Things to be like, undoing Generations, and in season 2 he focused on changing the parts of Picard's character that were too major to stuff into season 3.
Voyager wasn't syndicated, it launched UPN, which was Paramount's hope for Star Trek since the 70s. Then Enterprise rode out the network almost to its dissolution. We wouldn't have had a project ready to morph into TMP without Phase 2 and the planned and then abandoned network.
"Spock's Brain" actually was licensed and performed by a community theater as a comedy. The teaser and part of the first act used to be on YouTube.
I thought that point about the season finale was the whole point of the episode. Pike and his style weren't right for the situation. He was like a caricature of Picard without the tactical superiority to back it up.
It also might be another reason Enterprise was the ship kept out of the Klingon war.
From what we've heard, about the only thing Roddenberry liked about the idea for Captain's Holiday was that in addition to the heterosexual couples in the background , he could have gay couples. The writer thought it would get the episode dropped, and in Chaos on the Bridge, Berman was very direct about having to stop that in its tracks.
If it was Roddenberry and not his power tripping lawyer or Paramount who killed Blood and Fire, I expect he was being petty about how Gerrold went from adoring him to arguments and mutual disrespect during the calamity that was TNG season 1.
I'd say TNG mostly stopped exploring new frontiers halfway through season 1. Farpoint promised exploration, but soon the ship is ferrying diplomats and scientists and answering Federation distress calls. The worlds are new to the audience, but not the characters.
