Holy hell, the miniskirts. I know it was progressive for its time, women's lib, etc. But: Female officers bending over console, butt swell hanging out. Almost every episode, over sexualized women needlessly emotional, constantly falling into male arms. Barely clothed, wisps of fabric. Spock saying that Kirk's alter ego trying to rape his female officer made him interesting.

I'm at episode 14, 1st season. Is the rest of the series like this?

That said, there's a hard, pure science to it I haven't seen in later star treks. Can see how people then would find it fascinating. Also gets deep, in a weighty, high drama way.
