Everything I read was alright. I expect a book of that size to have a lot of build-up, so I'm not complaining about it being too slow. And I liked the characters and the premises and the world building. But—call me narrow-minded all you want—I had a hard time taking anything Sanderson's written seriously after I found out he's a Mormon.

I was so disappointed reading this after the great 3rd book. It was just ... messy and boring at the same time. Maybe I'll try the 5th book sometime. Maybe not. It has no priority right now at least.
