The trouble with Tribbles

I ran across an old star trek episode recently, and it was a lot better than I remembered. Aside from the above, most of what I remember from the show is the crew showing up on the same planet until Kirk fights, makes out with an alien or gives a hammy speech about freedom, while Spock raises an eyebrow and says: 'That's illogical' But it was an actual well-thought out TV episode with good writing, good acting, etc. It checked out as one of the best on the wikipedia page. I immediately sought out one of the worst, which was indeed terrible. But the ratio is pretty close to 50/50. There's such a thick layer of nerds, irony and self-parody on the whole franchise that you'd almost forget that it actually was pretty revolutionary, I mean the show is from the sixties and there's a black woman and an Asian dude as valuable crew members. Sure, they're secretary and driver, respectively, but still. Being produced by Desi Arnaz and Lucille Ball might have had something to do with that.
