Funny you should mention that, ADM, since, when I was watching BB, I couldn't help but think that none of the Batman ladies, or "leading ladies" in superhero franchises in general, are worth anything at all. Basically, the only role they serve is to be loved by and then rescued by the hero. Once in a while, they'll show a little spunk, get a little dirt in the villain's eye. But ultimately, they're kidnapped, absconded, and put in a precarious situation that only the hero can save them from. If they're lucky, they'll have the opportunity to say something profound that causes the hero to think about his actions and other such introspective ideas. Take the Spider-Man films. Three films. Three climaxes. All three are set up by having Mary Jane kidnapped and Spider-Man having to rush in to save her. I don't think Kim Bassinger screamed even a third as much as Kirsten Dunst has over the course of this trilogy. Honestly, part of me wishes they'd remove the whole romantic interest part of superhero films at all since they exist only as plot devices but are basically worthless outside of that. Take the pinnacle of Batman movies, for example, Batman & Robin! They cast Elle MacPherson as Julie Madison... but why? Why did that character even exist in that movie? She did nothing! Yeah, obviously the example is just a turd in a larger pile of crap, but still...

As Catwoman said in Batman Returns, the only thing females in superhero movies do is, "wait around for some Batman to come and save you."
