Meh, mistborn, mess

I'm always looking for fun reading for the cardio machines, but Brandon Sanderson's Mistborn trilogy doesn't seem to be doing it. When I make it halfway through a book and have no impulse to finish, it is not good. Aside from the fact that few of the characters are compelling, their interactions are not that interesting, and the magical universe is not terribly fun, the writing is beyond repetitive and clunky. Let me give you an example: one of the primary ways that the magicians, for lack of a better term, work is by burning metals that give them specific powers. They can fly through the air by Pushing or Pulling on metal. (Great terminology.) This is painstakingly explained the first time that the hero does it, balancing himself with a coin dropped here, a window sash there, a guard's armor hither, a thrown coin thither. You get the idea, right? Well, then we go through it yet again when the hero teaches the scrappy gutter girl with amazing powers how to do this, and we have to hear her first-time experience -- which adds next to nothing. I blame the editor as well as the author.
