Well, they couldn't exactly have the Battle of Hogwarts because the D.A. wasn't implemented in the movies. I already knew there wouldn't be a battle scene at the end and didn't bother reading a shred of what was already in the movie.
I like how they portrayed Malfoy, but I do not like how they did the closet scenes. It seemed too random... Pointless. Oh, quick nerd moment here. I laughed with my family that the bird in the closet was actually Schrodinger's cat.
