Unpopular opinion:
I liked the boob window. It was completely impractical, a center for jokes, and totally unnecessary...but it was fun.
Power Girl is, was, a fun character. She truly enjoyed being a superhero and saving the day, because it was one of the few things in her life that made complete sense. When people were in danger, it didn't matter that her past was a muddled mess, her personal life was next to nonexistent, or that her secret identity
was nonexistent, she would just swoop in and save them. Because, as a superhero, that's what she did.
And she was tough! Not just physically, either, though Karen was one of the three strongest women on the planet at any given time. She didn't take s**t from anyone. She was a vital part of the JSA, and the leader of the All-Stars. You can't lead a legacy team like that without being made of some stern stuff.
Compassionate, too! Remember in her series (v. Jimmy Palmiotti/Amanda Connor), when a kid was blackmailing her? She could have beat him up. Hell, she could have told his mother on him and let
her kick his a**. But nope, nope. She went with his demands, and ended up getting her way in the end.
Without hurting anyone.
And what about her friends? Karen
loves her friends. Not just Terra! During JSA: Classified, when Psycho Pirate was manipulating her emotions and memories, she sought out Huntress, her very best pre-Crisis friend, if only because she could remember cherishing their friendship.
I'll only mourn Kara Zor-L if she loses these qualities. If she goes from being a tough, outspoken, fun, compassionate woman to being some sort of shrinking violet (and not the Legion kind), I'll be mad as hell. And
then I'll talk about how DC is 'ruining' her.
