Hell yes to Harry/Luna! In the books I was leaning more toward Ron/Luna, but in the movies her and Harry are just so spot on together. The actress who played her... I can't remember her name... but she did such a brilliant job, I think. Movie!Luna had this air of tranquility about her that sort of gave weight to her oddities, if that makes sense. She could so easily have been overplayed and hammed up.

LOL, emo!Draco! He should just quit the wizarding world and become a folk singer, I think.
