excellent points on your last two posts, 1,000th reader
to repeat myself for the 1,000th time, there is no evidence, one way or the other to state whom is stronger than who in the aforesaid battle, except for circumstantial evidence.
and the end result was the same in both book and movie. the battle was finished by the horns of the rohirrim who came to save the day. the only difference was that gandalf was prone on the floor in the movie - a point I finally conceded about 6 months or so ago on this thread if I can remember correctly.
I was just glad to get somtething akin to the book in the EE edition of this movie, even though parts were different.
PS - Come the World War III, with a few of us lucky (or unlucky) ones sitting in our nuclear bunkers or under a mountain, we will still be here arguing whether Gandalf was stronger than the Witch King............
