I think to enjoy TOS you have to put on your 1960’s goggles and remember it wasn’t really considered sexist at the time. The line “I just can’t get used to a woman on the bridge” from The Cage may be considered unacceptable today but not then. Also most shows from that time were campy af. Remember Batman?

Considering the small budget NBC gave them to work with they got a lot of show out of it.
