These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
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.
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.
