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).
Fridge Logic: In the episode "Small Problems", a Horde scientist tells Bow, who's disguised as a Horde Inspector, that he'd developed the enlarging formula before he developed the shrinking formula, but that Hordak didn't want to make the Rebels bigger. Why Hordak never thought of using the enlarging formula to make his own troops bigger, probably just illustrates how dumb Hordak actually is.
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.
