I've always loved this episode, and now it turns out the deeper you look, the more there is. So much texture and detail on the screen, so many nooks and crannies in the story. It was more expensive to make than "That Which Survives" or "The Cloud Minders," but boy was it worth it. "Miri" did not roll off an assembly line. It was finely crafted.
Definitely one of the better ones of the first half of the series. Not without it's flaws, but worth a watch. And as I've said before, for one of our crowd, it was the first episode he ever saw, and it hooked him.
