Think about how fun "Assignment: Earth(TOS)" is. Sure, it's a Star Trek episode first and foremost but Kirk, Spock and the other crewmembers aren't even the main characters in the story and don't even show up in quite a few of the scenes. It's a Gary Seven and Roberta Lincoln story and both characters (who I might add never again appear in onscreen canon) do a commendable job of carrying a story that also has none other than Captain James T. Kirk - William Shatner - in it.
Yeah, it was intended as a pilot for a spinoff series but that doesn't change the fact that guest stars and supporting characters define that episode and did a commendable job.
