I was fine with Tolkien's portrayals. Never could figure out, tho, why Gandalf had to put a 'shutting-spell' on the door to the Chamber of Marzabul (sp?) -- felt out of place since everything else he does is by inherent power (obviously).
I was bothered by that as well, until I read the Silmarillion with that topic in mind.
A "spell" is something like this: Gandalf wants the door to stay closed, but he doesn't have time to stand around and force it to remain closed with his mind. So, he places a "spell" which is like his other powers, except he doesn't have to concentrate on the object. However, the Balrog begins to exert his own power, making it necessary to concentrate on the door so that he could add more power to the "spell", and the force of the opposing wills blasts the door to pieces.
Think of a "spell" as just being residual power. It continues to be active until concentration on it changes its nature.
