Mighty Morphin' Power Rangers was the coolest ... and then it came back as Power Rangers Zeo and Power Rangers In Space and Power Rangers Time Force and Power Rangers Ninja Storm and damn, there are almost 30 of these things. That's probably why I wasn't too excited about the 2017 Power Rangers movie (aside from the fact that it was bland in a way that was almost offensive). The Power Rangers never left. It's the same reason nobody feels nostalgia for the Law & Order franchise.
What We Should've Gotten: Gargoyles
Gargoyles is one of the most underrated cartoons in history, and should be mentioned alongside greats like Batman: The Animated Series way more often than it is. It concerned a group of ass-kicking gargoyles who get turned into stone in medieval Scotland and are awakened in modern-day New York City. While there, they make it eight episodes before one of them accidentally shoots a police officer with her own gun by accident. This show was not fucking around!
It also had two incredible villains: the guy with the coolest name in the history of both fiction and nonfiction, Xanatos (voiced by Jonathan "Commander Riker" Frakes), and the formidable female gargoyle Demona (voiced by Marina Sirtis, aka Counselor Deanna Troi), who is still a fucking role model as far as I'm concerned.
