I haven't read the current Birds of Prey, but the old one was pretty good. Not really a Black Canary fan but I love Oracle and Huntress.
I never gave this any real thought until now, probably because I never once considered it to be more or less interesting to have a superhero or powerful character be female. Appearances (hot/not, and that whole deal) never enter into the equation for my liking characters aside from how they're dressed, be it a neat costume or just great fashion sense. It's more 'wow, that's awesome', not 'wow, that's totally hot', if you get my meaning.
While it is an interesting question to ask, it's kind of sad that it needed to be asked at all because people should just be people, though obviously that's not how it really works. That being said, the more female superheroes there are, the closer we get to that ideal of it being a non-issue. I wish there were gay superheroes and no one cared about that little detail. Wouldn't have the slightest effect on the ability to fight crime or evil, so a person's gender wouldn't either...well we can dream.
That wasn't a comment on Rogue11, it was a comment on the way things are in the world....so no, I don't think it's weird to like female superheroes more and if anyone tells anyone else here different, in the words of Spike, "get stuffed!"
So, this topic stuck out to me, and I just thought I'd add another perspective! I'm a straight male, and I have to say that many of the female heroes impress me much more than the male ones. I grew up watching Buffy right along with Batman and Superman.
In my adulthood, I find that the female heroes really set themselves apart from their male counterparts. It's not the tight clothes or their figures. In fact, I find it to be something much deeper. In them I can see something that flies in the face of society's norms. This isn't to say that it's unplausible for a female to be a hero, but culture tends to put much more emphasis on the male as being the musclebound hero who saves the day. The idea of a female doing the job, and oftentimes doing it better, is somewhat liberating.
Watching heroes like Buffy go as far as to have to save their boyfriends, who are portrayed as weaker than they are, furthers this idea. I really think it has an underdog kind of feel to it. Maybe it's just because I grew up as kind of a wimp, but watching heroines has always drawn me in a little more than the males.
Not to say that I don't enjoy the traditional male superhero. There's just definitely a different kind fo appeal and connection made with the female.
