I was a bit disappointed. Because of the ending.
I'm going to watch it again in the next few weeks, and let this film sink in.
However, yes; Harry, Ron, Hermione and Hogwarts-, you will be missed. So much. I can't believe it's over. Films do excite me, but nothing ever reaches the level of an HP film. And I just love its world and the people in it! I will be writing things on this soon. I'm just a bit numb right now.
