This movie expanded the Wizarding world you got to see outside of Hogwarts even more then in the Deathly Hallows movies but also you got to see some history and see the differences between Wizarding cultures!
This was also my fave because we saw tom riddile in the makings of being the dark lord. I also liked the courage and dobby was so kind in protecting some one he hardley knew
It's the first time you get to see the main characters in the real world as adults facing a problem together and not relying on a parent figure or a professor. They're on their own in this movie!
