Okay, here's what bothers me (I know, one of the many things
): When we see the Witch-King being powered up or suited up or whatever, Gandalf says, "Sauron has yet to reveal his deadliest servant." It makes it seem, to those not paying attention, or paying too much attention to their dates, that this is some new bad guy. But shortly after that, Gandalf says, "You've met him before...He stabbed Frodo on Weathertop." These two statements seems contradictory. Maybe a few more words, like, "And now he is more powerful than ever," would be helpful.
I know that many of you see this scene and say that this is evidence that the Witch-King is more powerful. But what of Gandalf in Fangorn? And a new hat doesn't impress me.
