Harry Potter and The Prisoner of Azkaban/Awesome

• In the book, Hermoine slaps Draco, leaving him rather stunned. In the film, she is about to, but relents. He seems pretty smug about this, and then she PUNCHES him in the face. And the Fandom Rejoiced (as did everyone else).
• When Harry uses the Patronus charm to protect himself and Sirius. Every time I hear him shout "EXPECTO PATRONUM" it sends shivers up my spine.
