If they can manage to have 90% of the orcs without a hunch back, then I'd watch it AND enjoy it.
I'm not paying $ to watch the Hunchbacks of Notre Mmar.
In all seriousness, though. I don't think it'll break the mold, unless all of the writers were the story-board for TBC/WotLK. (It would explain why the story has gone down ab it. I like MoP, but I have to admit that like 40% of the main story is a bit cheesy. Like, Prince Anduin: PI every part and a half of the 5.1 alliance quests. I swear, those Royal Bodyguards must be some of the dumbest people in the world.) And the special effects... I hope they aren't cheesy as f.
So that's all I hope for in this movie: Brilliant script and story. And good special effects for them special moments.
Oh.. and no hunchbacks.
