Who do you think is the most interesting character in Harry Potter and why?

i say Hermione... She's beautiful and smart. I think she should've been the main character so that it would be Hermione Granger and the Goblet of Fire... I know it doesn't even sound right but I'd have watched it anyway... OR she could've at least dated Harry Potter. I know it would've been obvious and boring but I'd imagine if they had kids they'd be real smart and beautiful. More than Rose--- the child she had with Ron. I know that not much was mentioned about the kid but Ron said she had brains like her mother...
