Now for my annoyances.
There's spoilers here. Obviously.
I didn't mind that the final battle with Voldemort took place outside and not in the Great Hall. That's fine. But I hated that there was NO ONE there to witness it. I love the part in the book where he kills Voldemort and there's just silence for a split second before the entire place erupts into raucous cheers and everyone is hugging Harry. Love it.
Fred's death should have been given more screen time. I thought they covered Lupin and Tonks' deaths exactly like in the book, but Fred dying is such a HUGE part in battle. I just feel like it did a disservice to his character.
Percy should have been in it. They had him in the background at the very end, but I don't know why they even bothered having him in the film if they didn't even introduce the fact that he came back to fight with his family. Maybe it'll be in the director's cut, but it's still stupid.
Harry didn't fix his own wand with the Elder Wand at the end. I don't know why, but that annoyed the **** out of me.
I wish Harry had gone back up to Dumbledore's office at the end and had the scene with all of the headmasters and headmistresses applauding him and Dumbledore's painting smiling down at him and crying. So moving.
And wtf was up with Voldemort and Bellatrix disintegrating when they were killed? So much less powerful. Plus, the pacing for Bellatrix's death was terrible. They did not do her death justice at all.
I wish Kreacher and the other house elves kicking ass had been included because that part is awesome as hell.
Wormtail wasn't even in this. Uhh, okay. Where's the resolution for that? All of the Marauders died in the books...but not in the movies apparently.
No Grawp. If they weren't going to have Grawp then they really shouldn't have even had the giants at all. I would have rather had them spend the time and special effects on the house elves.
This isn't really a complaint...more of a question, but why the heck was Blaise Zabini with Malfoy and Crabbe in the Room of Requirement instead of Goyle? Do. Not. Understand.
I also didn't understand why Harry, Ron and Hermione had to put dittany on their hands after they got off the dragon when they didn't even have that spell that caused the treasure in the Lestrange's vault to burn as well as multiply. In the book they used it for their burns from the treasure, but they had no burns. Why even bother?
And I think that's it. At least for now.
I know, I'm too much of a purist, but it feels nice to get that off my chest.
