Awesome Music: The epic opening theme music — "I am Sheee-raaaaa!"
Ensemble Darkhorse: Shadow Weaver and Sea Hawk. The later becoming the fan preferred boyfriend for She-Ra.
Girl Show Ghetto: Interestingly avoided; most of the male audience who watched He-Man also watched She-Ra. But on the other hand girls didn't suddenly start liking She-Ra just because the main character was a girl. The toy line, however, didn't fare as well (see below).
Harsher in Hindsight: In retrospect the Horde occupation of Etheria and the rebellion fighting them seem unfortunately similar to the Cardassian occupation of Bajor, only with less bloodshed and terrorist acts. Made even eerier by the lead female characters of each plot having names that rhyme.
Periphery Demographic: While made with girls in mind, the show was careful to keep in plenty of action and plot to appeal to the boys who watched He-Man.
Rescued from the Scrappy Heap: Bow; his new action figure, which is in scale with the rest of the Masters of the Universe line and show accurate head (complete with mustache) has helped soothed a lot of complaints about him and his original figure.
The transformation sequence is grand, especially for the time and budget Filmation had to work withnote Of course, they almost certainly put an above-average amount of budget and work into the transformation sequence, as it would be seen at least Once an Episode, if not more.
The backgrounds were lavishly painted as well, even if the animation going on wasn't too complex.
