Even people who don't play World of Warcraft will probably be impressed by how good the cinematics for the game are. Specifically the World of Warcraft: The Burning Crusade Cinematic Intro and the orginal intro (also downloadable from the Blizz site.)
If you're not impressed, you don't know a damned thing about computer graphics. These cinematics are better than (almost?) any fully CGI-rendered feature film. I can't think of a single release that tops them. The Final Fantasy movies PALE in comparison.
So, on that note, I have to say it's a tremendous shame that the WoW movie won't be done by them. It will be live action. My Blizz connection says, "The Blizzard Film Department will stay focused on in-game stuff."
