Somebody Is Going to Die!!!

I don't think that's limited to just people who aren't avid comic book readers. I've been reading them for a long time, and while familiar with the human/matrix version of Supergirl, I never knew that version of the character to be such a distinct take on a character. I was under the impression that she was more of a patchwork character, who DC was constantly trying to find ways to make relevant or mainstream by adding new facets that never seemed to catch on; leading to a characterization that was disjointed and poorly defined. That's not to say that, that's actually what it was, but in contrast to other characters, I don't think the Linds Danvers version of Supergirl seeped into mythos of the greater DC cannon as to become ubiquitous.

My Impression of the Supergirl tv show wasn't so much that they were turning her into a female Supergroup, so much as following her first comic book iteration, to some degree. In contrast to the iteration we saw in Smallville, or the post-Infinite Crisis (?), or New 52 versions, I can make my piece with what we have. I don't think this will be a popular opinion, but I couldn't stand Kara on Smallville. I didn't care for Laura Vandervort in the role, I didn't like the character's arrogance or that she was older than - or at least the same age as Clark; and I especially hated that she effectively became Supergirl before Clark became Superman. That last part wasn't anything specific to her, so much as how it played into the running theme during the final few years of the show where Clark's role as a hero became muddled in favor of other heroes, in an effort to run out the clock and not have him be Superman until the end of the series. The result being that Clark was all but the last hero to come into being, when he's supposed to be the first, and set the standard of those who follow.

The post-Infinite Crisis comic book Supergirl, or whenever it was that she was rebooted as another Krypton survivor, discovered after a Kryptonite meteor shower, seemed to be riddled with the problem of the writers not knowing what to do with her; indicated by her possibly being sent to kill Clark and Kryptonite poisoning. The New 52 version was straight up obnoxious in her utter disdain for everything and everyone, leading her to join the Red Lanterns because of her anger.

I did like the New 52 Power Girl from Earth 2.
