out of 10
Ugh, wish this series had a better book to cap the first half. The ending isn't what I find frustrating at all - in fact I consider it pretty good and interesting as part of world building and setting up for the second half.
The part I dislike is all the current-world politics that Sanderson throws into the book - Kaladin becomes a therapist, Renarin's love story, and things like that. I prefer a fantasy world that's not influenced by modern times and culture shifts, and this book did not deliver on that front.
