TOS has the best tone/feel of all the Trek series’, but I’m not keen on the Technicolor sets/costumes, the episodic storytelling, or the steadfast focus on Kirk/Spock/McCoy. TNG & especially DS9 did better jobs utilizing and developing their characters.
The Kirk/Spock/McCoy dynamic is the show!
I love 'em, but it would’ve been nice if there’d been some Scotty/Sulu/Uhura/etc.-centric episodes in the mix.
What about when Uhura forgot how to read?
I agree with your assessment by and large, but I really really love the technicolor sets and clothes in TOS.
