[Okay, so apparently the wikipedia article's worth of knowledge she has on the subject doesn't really cover the whole story.]

There've been a lot of versions of the Superman story told. TV shows, cartoons, comics.... apparently something called a "reboot" happened a lot. As a character, she's been around since the thirties. As you might imagine, the character was fairly different back then, and unfortunately, some part of that has clearly stuck in the public consciousness.

I'm glad to hear that's not how she is now. Your version sounds like she might have actually got me reading comics.
