Administrator's Note: This thread has been split from this one.I haven't read much of the "new" Supergirl... just that she is Kal-El's cousin, Kara...
I kind of like the idea of the "hero-worsipping" aspect of Kara in her first decade. It's like you've found your long lost cousin... seen him do great things and he's your ONLY connection to your family (yeah, I know Zor-El and all were in the Survival Zone, but Kara and Kal didn't know that). You would have a real bond to that person and look up to him and emulate him. It's natural. I have an older cousin that I emulated til I became my own man. My step-son has an uncle he emulates. There's a bond. Kara surely felt that bond with Kal-El.
I never cared for the portrayal of Power Girl, especially in the '70's. It was like "I'm Superman's cousin, but I can't stand him". I hope the current incarnation of Kara Zor-El isn't the same as Kara Zor-L.
BTW, wasn't there a Supergirl story a few years ago that was ANOTHER Kara who came to Earth and met the Matrix Supergirl? What happened there?
