| The Witch King owns Gandalf at the gates of minas tirith in the book as well
The Witch King was the greatest of the human's who took the human rings of power
Even though he was once man, the rings are still powerful and being a wraith and all, he's pretty uber
Gandalf being a maiar means little.. Saruman after all was killed by "conventional" means... indeed given that Sauron was a Maiar himself and was the big dude in Middle-Earth (more powerful than even Gandalf), there is a good chacne there are shades of power within the Maiar |
