H is for Hagrid, Hermione, Harry....must stick with Harry.
I've already addressed Rowling's brilliance with characterization. Out of all of her characters, none is more perfect than Harry Potter. Harry is a classic rags-to-riches boy. He's the awkward average nobody that proves to be braver and smarter than even he thinks he is capable of. His strong sense of right vs wrong makes him a character everyone wants to root for. He makes us think we all have greatness (and magic) inside of us.
Love Harry Potter.
