So Harry Potter is coming up and I've decided to do a series of weekend polls dedicated to the franchise. Of course my questions will be more tailored to the films, so all of you book lovers who want to just shout at me for not reading them be quiet. One of the biggest running jokes of the series is that every year there is a new Defense Against the Dark Arts (DADA) teacher that at the end of the year resigns so to make way for the next. We've seen six years of Hogwarts and therefore six DADA teachers. Who's Your Favourite?
