Why couldn't they just get actors who resembled the original actors?
My biggest problem with this movie is that it doesn't feel like the first movie at all. All the characters look completely different (except Coreander; was it the same actor?), the world looks different, and the tone just isn't the same.
Anyway, if they would've just gotten actors that resembled Bastian, Atreyu and the Empress that would've markedly improved the film in my eyes.
