This is a reasonable Short Trip. Although we hear a lot about the Hihmakks, we don't actually get to "see" them at all save for one, and there are no other direct characters for the Doctor or Leela interact with, which means there's more opportunities for little moments between the two characters. This short trip is more a case of an atmospheric mystery, the examination of a scenario, and whilst maybe not 100% perfect, it pulls it off quite well. It just about manages to hold up for the duration and comes off fairly well. Overall nothing outstanding for the range, but passable for what it is, thanks to a reasonable plot line.
