The Hidden Kingdom

Gandalf Grey is a menace. First he sends Thorin and his team on a wild goose chase for a kingdom that other archaeologists have spent fruitless years trying to find. Then they actually find it, depriving Thorin of the (well-deserved) chance to say "I told you so." And then there's the infuriating antlers in the throne room and the really annoying dungeons.

Oh, and the comatose elf. Can't forget about her.
