Do you think he lived up to being the villain we all hated/loved in Warcraft 3 TFT? Or do you think his presence in WoW made it a bit silly?

In my honest opinion, I thought that his story sucked in Lich King. He was always threatening Azeroth with rampant destruction yet he never really did anything that made us feel like we were in danger. The voice acting didn't help, either.
