Except they have ALWAYS been playing with the "legend" right from the get go. When he was first introduced, Superman couldn't fly..he only made huge leaps and jumps. He started flying because the Fleischer animators had trouble animating him leaping and bounding in the 1940's cartoon series. Plus he wasn't invincible as "only a bursting shell" could penetrate his skin. Even Clark's adopted parent's names kept changing depending on the media. (Radio, Movies, Comics...) Heck, the whole Jimmy Olsen character was a radio invention and not from the comics. Good website on all these changes and evolutions: https://www.quora.com/When-did-Superman-gain-the-power-to-fly-and-was-there-a-good-explanation That's why I don't get bothered by "deviations" from what I grew up with as being "canon." "My" canon was an earlier fans left turn. I just go along for the ride. And to stay on topic, this Supergirl strikes my wife and I as our kind of ride.
