>Also, Roddenberry employed established scifi authors like David Gerrold to script episodes.

While established SF writers wrote episodes for the original series (Harlan Ellison, Theodore Sturgeon, Theodore Sturgeon, Norman Spinrad, etc.), David Gerrold was a recent college graduate and "The Trouble With Tribbles" was his first sale.

For me, that’s the best part of the TOS era.

It’s nice to watch something that highlights the best of humanity in a future setting.

Almost everything else in SciFi is dystopian. But ST is a rarity. And it’s all the more beautiful for it.
