I liked the plot and the story development. Sanderson is so good at finishing / making stories happen / getting things done. So impressive.
However, his voice in this book was bothering me. The sentiment and the language just seemed too modern and too American. There also seemed to be more pandering to fans in this book than in others. Some of this worked well (most of Adolin's arc) some of it fell flat for me (Kal reusing the honor is dead line (but other people loved that, so i am probably wrong)), and some of it that seemed like bad fan fiction and should have been cut (the library scene, a few character or narrator musings / sermons that seemed gratuitous).
By the end of it I was satisfied and like it. But this was my least favorite Sanderson book.
Other things I wished were different:
I don't like the "I saved my city in my pocket dimension" detail. I think it weakens Taravangian as a villain.
I don't like that Taravangian captured the Blackthorn as a cognitive shadow.
I so wish we had a Mishram rampage where she burns the world down. I have been Mishram obsessed for a few books now and this just wasn't enough. Too many promises, not enough payoffs.
