It was entertaining, and that was what I was looking for at the time. It had some novel ideas and I thoroughly enjoyed that because it made it seem less derivative. Some of the dialogue was terrible, but that doesn't really stop anyone (if it did, Star Wars would never have taken off).

In fairness to Sanderson, I think people who bash his writing style are often some of the biggest hypocrites I've ever found. While it's not writing at the level of a literary classic, it's not really significantly different from other works that the Sanderson detractors seem to like, such as books by Martin or Jordan, or (shudder) Goodkind.
