I really don't care that much about Arthas. He was kinda cool in WC3 but I don't really want to see a whole movie about him. I want to see more aspects of the Warcraft universe than just a villain focused piece can really offer.
If he's the protagonist I can't imagine liking the movie - his story has been told and while it's exciting to WANT TO KILL HIM in WoW, it's not that interesting to go see a movie about his history which is already out there. I'd actually have liked to see a movie not based on the existing lore characters - while they should have a presence but not dominating the film - and actually creating new characters who reshape the WoW universe in their own way.
