From what I understand the (written) content is actually quite well written and non-juvenile. It's presented in a mature fashion. Teens, I think, would get bored with this quickly, since all they really want to do is "Do the chicks!" and they can do that just fine without extra rules. Plus, most teen groups are just a bunch of guys, and getting too sexual in all-hetero guy groups gets old fast.
I DO find most of the art to be not to my tastes, and not well reflective of the spirit of the other content of the book. I fear the art is there primarly to induce shock value and get free advertising from people objecting to it.
This book is not for everybody. I don't know if I'll bother getting a copy or not.
Frankly, though, I'm getting sick of having to wade through a discussion on the merits (or lack thereof) of the entire book (like anybody's seen the whole thing anyway) when thread-posters are trying to discuss a specific thing. I know I'm contributing to this right now, but I still think Trainz should have been able to start a discussion on this PrC without starting another discussion about whether the book is a good thing or a horrible thing. From here on, let's just talk about the PrC, ok, and if you're anti-BOEF, then just pretend it and the threads about it don't exist.
