All right, I've been tossing this around in my mind a lot, debating if I should throw in, or just ignore it because I'd only be echoing what everyone else has already said. Anyway, I guess that I've decided to add my two cents.
Book characters:
Lupin: Without a doubt. He's kind, intelligent, and loyal. He's also a little wounded, which makes me want to hug him forever, and a little dangerous, which makes me want to do other, naughtier things to him.
Snape: Intelligent, complex, dark - what more could a girl ask for?
If I had to pick one of the brat pack it would probably be Ron. I can see him making someone (Hermione?) a good husband.
Movie Characters:
Snape: How can you NOT love Alan Rickman? That voice - OMG! I rest my case.
Lucius: Arrogant? Yes. Evil? Definitely. Sexy? Duh. And that pimp cane.... *swoons*
Oddly, Lupin left me a little cold in the movies, despite Thewlis portraying him beautifully.
Too young, but still noteworthy:
Draco: In the same vein (vain?) as his father, there's just something about that disdainfully curled lip that makes my knees go to jello. I don't generally go for blondes, but he's got the right body type: tall and lanky.
Ron: Especially in the latest movie, he's really started to shoot up and fill out nicely. The shoulders hint that he'll eventually end up being a little more solid than I like my men, but right now he's just about perfect.
Fred & George: Fun loving and yummy! Sandwich anyone?
