>it was a bit too much of the social stuff
Because clearly none of the other series focused on social stuff, except...
TOS, which featured an interracial cast (and kiss) in the 1960s, where nearly every episode was thinly-veiled commentary on communism, where they visited a literal Nazi planet, where they had a black woman as a bridge officer (in the 1960s)...
TNG, which went into deep moral arcs, looked into military tribunals, witch hunts, had entire movies about mindless bloodlust and environmentalism/colonianism, and so much more...
VOY which.....honestly, if you don't get the point by now I'm not going to spend more time listing examples.
Star Trek was BORN "woke" and has always been there, and anyone who claims otherwise was never really paying attention. Star Trek EXISTS because Gene Roddenberry put social commentary into his show "The Lieutenant" which was too controversial for the actual US Military so he had to make a new show set in the future to make all the same points but with less oversight from crusty generals.
I interpreted the GP as saying "social stuff" as in focusing on social interactions between the characters instead of having more action & adventure. "maybe because it plays mostly on a station instead of an exploration vessel" was what made me think this.
