If I was 15 and I read this book, I'd probably give it four stars, and my reasoning would be; "oh my god Catwoman is hot and had sex with Batman!". Then I grew up and found real women are better. Of course the "controversial" end to the book is getting attention, and I'll spoil it here- Catwoman and Batman have sex. Wow. It's 2011 I'm not sure why that's a big deal on paper. I do think what's a big deal is DC shouldn't be marketing this book to 11 year olds, I hope they are targeting an older market. Also, if this is a new #1, lets start over with the Batman/Catwoman relationship and build the sexual tention over many issues. It would seem more natural then all of the sudden at the end of the book Batman shows up and they do it.
My second instant thought to this book is, I bet this is how nerdy comic book guys and pre-teens thinks or wishes women would act as Catwoman runs around with almost no clothes on and shows off her over the top sexuality. If I was a woman, I wonder if I would find all of this a bit insulting.
All in all - Catwoman would have been better to keep ALL of her clothes on - 1/5.
