20. Ginny Casting Reductor Curse - Order Of The Phoenix
Ginny's character gets the shaft in pretty much every one of the Harry Potter films. In the books, she's a strong, confident woman who has a great sense of humor and is totally willing to have it out with her older brothers if they're being judgmental of her. In the movies, however, she's just sort of a blandish love interest for Harry. So it's nice when the films remember to remind everyone that she is a legitimately powerful witch in her own right. It's wonderful to watch them all practicing their spells on the mannequin, and then when it's Ginny's turn she just obliterates it with a proud little smile on her face. That's the Ginny that Harry falls in love with.
