With the Harry Potter franchise, J.K. Rowling created a truly immersive world of witchcraft and wizardry, capturing the imagination of the entire world. With a story such as this, there is literally no limits to what can happen, except the rules laid out in the story itself.
As such, there is an incredible amount of detail, and lore poured into the story, creating an entire world and society from nothing. However, while there are some of the tiniest details to explain seemingly insignificant aspects of the story and the world itself, that doesn't mean that there aren't some biggies left out.
Whether they are about the story themselves, or if some minor detail was left out when the books translated to the big screen, it's impossible to watch all eight movies and not have any questions at the end. While J.K. Rowling occasionally takes to twitter or interviews to try and fill in some gaps about the story, we can't be expected to read every single tweet or quote to make sense of our favourite movies.
Some are incredibly trivial and make no real difference to the over-arcing story, while some are bigger, and the omission of an explanation for which is more surprising. Either way, these questions went unanswered in the movies themselves, and they will haunt you.
