I enjoyed this one quite a bit. The Doctor (along with Jamie, Ben, and Polly) come to a colony on an unnamed planet. It seems Utopian, with Refreshers and machines to tone your body and repair your clothes, until they get the gist that something is up. Not only do the guards seem particularly interested in the ramblings of a crazed prisoner, but certain strict rules are in place. And there is mention of pits and labor sites. The Doctor is quite active in this one (some of the earlier stories would have him as an almost passive observer, in my experience) and works harder than any of his companions to solve the issues. One does have to get used to the "linking narration" (at first, every little thing is described and by the end, several minutes will go by without a lot of clues) but once you do, it's not too hard to imagine the scenes and to enjoy the adventure. My favorite Second Doctor story to date (though, due to the BBC archive wipe, only about the third one I've seen).
