That Dark Wizard scene. Seriously??!!??

Up to this past episode I was pretty content with the writing. But that scene between Gandalf and the Dark Wizard must have been the worst writing I have ever witnessed.

So you're telling me they spend a whole season building up this villain with henchmen and all. Just to have him be like:"Me??? Evil??? Never! And these mercenaries... I didn't know what I got myself into!!" And just seconds later: "What?!? You don't want to rule all of Middle Earth with me after defeating Sauron?? Well then I actually AM evil!"

You got to be kidding me!!!!
