The part I liked best in this article was when the author pointed out that "Kara enjoys being super (and Supergirl)". Exactly - she's not one of those clichéd contemporary "brooding superheroes" . As Time magazine pointed out last year, Kara "saves her city with a smile".. She clearly enjoyed being a superhero in the Silver Age comics, and also does on the TV show today (And so does Gal Gadot's Wonder Woman.)
As Sterling Gates wrote for the closing panels of his "Adventures of Supergirl" companion comics series: "I'm Supergirl....... This is my life. And I love it!"
