I am straying off course, but I think what I mean is illustrated (of all places) in the two Conan films. The first one has a magician character (the storyteller), and he was able to perform impressive magic feats (even to the point of possibly bringing the dead back to life). But...he has no certainty what he's doing will work. He more...sets it up...calls on the powers....and then plays wait and see to see what will happen. There is more than a tinge of madness to his approach, and he's clearly terrified of the powers he's calling on. He does not know what will happen.
In the second film, the same character can rattle off incantations as needed to accomplish specific tasks magically. It's much more D&D - memorize a spell, and then use it to have a fairly guaranteed outcome. It's a disappointing let-down compared to the earlier film.
While there is an obvious comment about science and religion in there, I think the awe is what makes the magic feel magical, and the taking it for granted is what makes it seem too mundane. Which is tricky, because elves *should* take it for granted, and it's the non-elves (like hobbit observers) who are in awe of what the elves can do.
I don't mind elves singing up a wind. I do mind elves seeming to have control over the wind, so that they can summon or banish it at will. I want them to *ask nicely*.
