Yeah, what was revolutionary in the 1960s (humans of all nationalities working together) wouldn’t have been enough in 1987, but I appreciate that it set the groundwork for the series as a whole.
The acting in TOS is over the top and often silly, but I try to watch it as a product of its time - audiences didn’t really want their shows to have an edge or get deeply philosophical back then, so Roddenberry and team had to sneak that type of stuff in where they could. I have a soft spot for TOS and the campy characters and still think it’s a fun lighthearted watch.
