The first six episodes of Sailorstars are devoted to killing off Neherenia from Sailormoon SuperS. Some consider this to be the "true" ending of SuperS. Then, along comes Sailor Galaxia with her Sailor Anima-mates to wreak havoc on the Senshi as well as the Earth. The Sailor Starlights first appear here as well. The focus is on Star Seeds, and the main villain, Galaxia, wants them. Chibichibi makes her first appearance here. This season also marks the first usage of the Sailor Star Song (for the opening credits) and Kaze mo Sora mo Kitto (for the ending credits). The past four seasons have all used Moonlight Densetsu for the opening credits.
Finally! Some closure! Not quite as good or as intense as S, but damned close. There is just one flaw. ChibiChibi. This is the single most nauseating thing ever animated. I fear the day they try to make an SD version of Sailor Moon - ChibiChibi is PERMANENTLY SD! *shudder* The starlights are pretty cool, and Galaxia is a worthy Villain. The ending is quite powerful, and is at least one reason to put up with the pain that is the thing with the basketball-sized head.
