Yeah, the first scene where Riker is in awe of the holodeck also says Data was in the class of 78, Riker is reluctant to accept Data's personhood (as initially planned), and since they hadn't introduced the replicators yet, Data describes the holodeck as using transporter tech in a way that sounds very clumsy and patronizing now.
After that they mostly stick to holodecks just being new on ships, and not usually controlled by a computer as sophisticated as the Enterprise's.
TOS had a proposed spin off for him, which would have ended up about his brother (played by the same actor) as first officer of a medical ship.
It would be astoundingly different after SNW.
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.
I've always thought the Romulans weren't just the Vulcans who rejected Surak's teachings, but also any who didn't have the physical ability to follow them.
Originally it was just based on Romulans not expressing any psychic abilities, but Picard also established that sharing personal details publicly as a major taboo. That would track with them being a mix of former enemies who are concerned with suppressing the rivalries that lead to nuclear war.
"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.
And when Enterprise did that, there were fans who insisted it was a retcon. It's something people beleived since TOS even though it was contradicted pretty soon after the Federation was even established.
There are several other things that fans have been certain of since the 60s (like saucer separation being irreversible in the field or Vulcans only having sex during Pon Farr) that weren't the production intention, but this one was blatantly impossible and it's very strange.
Wesley's mom, a main character, was initially going to be the ship's teacher. They shifted her over to the empty doctor position without changing much about her. Then they made a new teacher who was also changed to be a bridge character, as the ship's pilot.
While Riker and Troi are adapted from Decker and Ilea, Beverly was more extrapolated from yeomen Colt, Smith, and Rand.
Edit: specifically, their bios were mostly about a potential relationship with the captain, how competent they were (making them reasonable mates for him), and having the "walk of a striptease queen."
