After the padding of the previous episode, this one has an abundance of activity. The clone sent by Dragos manages to render Space Academy defenseless and Dragos sends it spinning into a nearby star. Jason meets a hideous monster in the cells, but he removes it's bracelets and it turns into a beautiful princess (nice one, Jason) and together they are able to escape from Dragos (finally!) and fly to a nearby planetoid (where they must deal with earthquakes and so on).
Sid Haig and Craig Littler are wonderful to watch. Littler has his best episode here. He's 100% committed to, and very likable as, Jason.
I also love the music. If you watched any Filmation shows in the '70s you heard all of this music and it's great to hear it again.
