No, I haven't read the books.
A month or so ago Sean and I had a date night and took in the movie - I wasn't expecting much, but we both enjoyed it - Sean said, "When does the next one come out??" I think he's just being a boy and waiting for the vampire vs warewolves part...
Anyway, about 3 weeks ago I read a great blog post by Kayla Aimee that addressed the Twilight thing and why people are so addicted. Please check it out here. She has some good stuff to say.
And then let me know what you think!
