Book could have been much shorter. Too many characters (Kaladin, Shallan, and Navani) have repetitious chapters that repeatedly drill in the same details.
I understand Kaladins particular mindset on a personal level, and do see what the point was. However there are ways to present it without being boring.
That said there was a lot of interesting events in the book. I feel it was worth reading, if only for the hope that the next book will deliver a climax. However the notion of ever rereading this book makes me shudder.
