Yo, what was up with that Burrow attack scene? That might've been the most egregious example of deviation from the books for literally no good reason at all. Excellent theory that it was really just to let Bonham-Carter showcase her acting chops, but she rocked all the accurate, relevant scenes anyway so it was thoroughly unneeded. Can you tell I have a lot of feels about that scene?

Also, they neutered a lot of Harry's sarcasm/dry wit throughout the course of the series, too!
