The TOS only appears jaded now becuase it has been seen so many times. For the 60's. it was very innovative. I bet you couldn't think of something better in a week, and if you did write an episode, you wrote it by standing on the shoulders of giants and building on what had gone before.
Jaded??? Are you sure thats the word you want?
Other than the setting, what was innovative about TOS? A lot of the people writing were TV veterans, with backgrounds in Westerns and Cop shows.(Roddenberry among them). Many of the stories they told were variations on stories seen on "Gunsmoke" or "Bonanza". Even multi-racial casting wasn't pioneered by "Star Trek" since contemporary shows like "Mission: Impossible" featured the same. And shows like "EastSide/Westside" the preceded it.
Polaris wrote "Tin Man" and contributed to "First Contact", both from TNG.
