DGD and I have been reading the Twilight Series. I haven't seen the movies, and don't know that I will. Books are so much better than the movies 99% of the time. Anyway, the reason I read the series was because I wanted to make sure that the content was suitable for an 11 yo. It's such a popular series and she had been bugging me to allow her to read them, so this was my compromise. I don't know that I would have read them if she hadn't been bugging. But Stephanie Meyer is a good author in that she really pulls you into the story and compels you to continue reading to the very end. As far as the topic (vampires and werewolfs), not really my cuppa tea.
So, if anyone was on the fence about reading them, I'd say go for it. They weren't "scary", it's more of a love story than anything.
Just my 2 cents worth.
