excellent review, and I couldn't have said it better myself. And your score was dead on.
Now here's a question for you guys. My oldest daughter (soon to be 16), is wanting to get into the Vertigo titles. She's very mature for her age, and I'm thinking this might not be a bad one for her to read.
It's up to you man. I read ElfQuest when I was like ten, I don't think it scarred me for life.
Having said that I had a hard time letting my eleven year old read Runaways, and I had a tough choice with RASL as well, but she seems to be handling both fine and loves them dearly.
In conclusion, you know your daughter better then us, if you think it is a good idea, then go for it.
