I watched (some of) TOS recently. And it basically erased one of my complaints about Discovery being "The Michael Burnhan Show." Because boy TOS is literally "The James Kirk Show." Like, Spock is there, McCoy is mostly there, but everyone else felt really really like, quintary, not even Secondary, just way way down the line.

I feel like everyone remembers Trek as "ensemble cast" from the movies and TNG on.
