The Sunwell is a great one, but the maker of it (Jack) has made an epic 30 min movie of the Burning Crusade raids. Burning Crusade: The Movie. He has also done one for Ulduar and working on an ICC one as well.
We need more of these kind of movies. I've tried my part once, but I'm no where near his ability. He's like the main one (or most known) for these cinematic movies. If you find more, lemme know
Here's my channel if you wanted to look through some. I know most don't meet the expectations of the UI, but I still incorporated music and some attempt at camera angles.
