One of the better 2nd season episodes
26 November 2018 | by jameselliot-1See all my reviews

The second season of Space 1999 was much weaker and cheaper than the first. Fred Freiberger, also producer of the cheesy 3rd season of Star Trek, was criticized for his production of the 2nd series. "Fred Freiberger helped in some respects, but, overall, I don't think he helped the show, I think he brought a much more ordinary, mundane approach to the series," said Landau.

Devil's Planet is a generic title that could have applied to any script about a planet. It utilized one of the oldest schticks in science fiction, a civilization run by stacked Amazons in tight costumes (Catwomen of the Moon, Abbott & Costello Go To Mars, Missile To The Moon, Queen of Outer Space and numerous pulp magazine tales). Koenig crashes on their planet and the queen is hot for him. At this point in the series, Landau was either alone or the crew was without him in other stories, like Dorzak, so the production team could shoot faster but this cost cutting technique damaged the individual stories. The rest of the story is about him escaping. A lot of questions are left unanswered. A good portion of the cinematography is aimed at the Amazons' buttocks. The cheaply designed transporter box they use to beam the prisoners to the planet Elena looks like a turnpike toll booth. The second season music is mainly horrible, a mix of TV disco and Love American Style garbage.
