Catwoman #1 and #2: Batman and Catwoman get it on while still in costume. Never seen anything like that before and I got a real kick out of it. I read that "10 Things We Don't Like" article and I don't know what the big deal is about the sex. It was well done and pretty tame. If it were any more subtle, it wouldn't be worth including.
Well, I didn't read it ($3 is almost a pack of cigarettes, and I've literally got a thousand comics I haven't yet read), so I can't really give my own personal take, but what it seemed to be--and from review pages did appear to be the case--was that the fucking at the end was just the icing on an objectification cake, and worse than that seemed to mirror earlier scenes where Kyle used sex as a weapon, or more technically a physical and psychological shield against someone she had previously known, and who had engaged in sexualized violence against other women she knew, if not her specifically.
Now, I can see how this could bother people. Sometimes women, when threatened, will try to seduce/fuck their way out of a situation. This is a valid thing to depict, since it happens in real life, like, literally all the time. Especially if the character's backstory is that of a street prostitute whose income and career were controlled by violent and domineering men. And you could even have the ending as is if the tone of the book was different. So what's unpleasant about it is that it doesn't really seem to be aware of any of it, or is aware and doesn't care, and tries to have its cheesecake and eat it too. I think for some people it's very difficult to square the constant set-of-ass-and-tits framing of the protagonist with a serious-minded I Spit On Your Grave-lite revenge trip, and a Tijuana Bible stapled to the end of the book only raises further questions about motivation and psychology, which Judd Winnick is neither interested in nor, one fears, capable of answering. Like, does the meagre validation of anonymous sex make you feel better after a straight-up murder? I suppose it's possible. Next time I kill a guy I'll have to try it.
Tl;dr version: Winnick brings up Serious Business, and him and March treat it with all the dignity of an Austin Powers movie.
Like I said, though, this is a synthesis of others' opinions, not my own close read of the issue (but I've seen enough to know these opinions are supported). But if that was a genuine confusion, maybe I helped? Maybe not.
