The characters are wonderful, and the situations are so fantastical that they make you (me, actually) desperately want to join in the fight against whatever vampire (or not) they're fighting.
Yes, the characterization is weird. They don't change too much.
But the books are fun! The situations are fun, and even relatable sometimes - despite the insanely drastic change between here and there. It's one of the better YA books out there, in my opinion, and I'm not saying this to shove it down your throat. I'm just tired of people being all, "you like twilight - waa loooseerr, fail, reed gud b00kz"
If you're one to show of your book-skills reading Kant and maybe Austen, then keep at it, but there's no need to degrade people because they freely enjoy some vampire romance (or vampire anything, for that matter - mmmm). Eh, either way, more Edward for me. :3
