Harry Potter show should expand on the world

We're all excited and let's be honest a little afraid about the HBO Harry Potter show but it's a opportunity to explore the world in detail that could obviously not be done in movies.

But wouldn't it be grand if we get to see things and explore storylines that were only hinted at in the books. Think of Ginny's PoV during the Chamber of Secrets or Sirius breaking out of Azkaban and fleeing to Britain or the rising tensions as Voldemort returns. Maybe we get to see the Order of Pheonix in action outside of Harry's perspective in the years 6 and 7 especially when open war has broken out. Maybe, Hogwarts under the Death Eaters can be depicted as well as the hunting down of muggleborns and their internment
