OK, I was a mid-80s boy who was into G.I. Joe, Transformers and He-Man hardcore, and transitioned into a fan of James Bond and the various 80s action stars (Der Governator, Stallone, Seagal, etc.). But along the way I became a fan of She-Ra and Jem.
The latter I found superior to its originating Spear Counterpart, for much the same reason I ended up liking Xena over Hercules. Both She-Ra and Xena were former villains who turned a new leaf, and spent the rest of their series redeeming themselves through heroics. In She-Ra's case, it was as the underdog. In He-Man's series, the good guys were clearly in charge of the place, and Skeletor and his goons were miscreants who occasionally showed up to try and overthrown the social order, but were always put down by He-Man & Co. While on She-Ra, the Horde ran Etheria as a police state, and she was an important part of the resistance. Maybe it was because Star Wars was still very fresh in everyone's mind, but I preferred the heroic rebels over the guys just maintaining the status quo.
(As an aside, has anyone ever noticed that being the heroic dissidents to an oppressive authority is one of the few times good, heroic and honourable characters are shown to be proactive? While in settings where society is portrayed as "good" and the villains as the occasional external threat, the heroes only ever react to the villains' plans? This might be one of the reasons I never really got into superhero comics.)
Jem was another property I'm surprised has never really been brought back (they bring back My Little Pony but not Jem?). Although much was made of the Clark Kent-style "love triangle" between Jem, Jerica and Rio, it was never an overwhelming part of any episode, and allowed to be a long-term plot complication (which was practically unheard of in 80s cartoons). And so much was going on in that series, from backroom corporate intrigue, to trampled egos, high fashion, vicious musical feuds that gave Tupac-Biggie a run for their money. The world of Jem is a place where women have a lot of power and personal agency while still thoroughly enmeshed in stereotypically feminine pursuits, e.g. pop music, high fashion, romance, traditional maternal roles. You'd think this would be a home run. Surely there's something here for the Hannah Montana crowd that's better than Hannah Montana?
