I'm reading the scriptwriters' guide for TOS and it's cracking me up in many places. It's so obvious that, from the very beginning, they were already aware of so many of the issues people complain about today.
First there's a multiple choice quiz, what's wrong with this scene?
Answer: C! Absolutely Kirk would not hug the yeoman at this point! That's unprofessional!
The Prime Directive gets explained. As I keep telling people, it's not never broken, it's just supposed to only be broken for very good reasons.
For people wondering how to write a stardate: you make up some numbers!
No saluting! Yes optimism!
There is so much "think of the budget" in here. Yes you can use the shuttle bay but only if it's relevant, we have to use miniatures. Yes you can have a space suit but please don't ask for zero gravity. And where aliens are concerned, you can have some makeup but please focus on the interior differences not just tentacles!
Honestly I think Spock is a better alien than, say, Jabba the Hutt, because as human as he looks, he's much more different on the inside. People like to dismiss Star Trek aliens as "forehead of the week" but it's kind of a stage shorthand for "we're about to discover a unique culture, these people are different from you in ways you might not expect."
