Warbreaker - Addicting little read, seeing as I finished it in under 48 hours. It doesn't have a patch on Mistborn, but it was fun enough.
The book has some fun with the themes it explores. I really liked the exploration of faith, religion, and tolerance, seen through Lightsong's attitudes and those of his priest, Vivenna and Siri's beliefs/prejudices, that one scene where Jewels actually talks, and various others.
The two princesses and their parallel stories were done quite well. Siri's was fairly stock, but still quite an enjoyable read, and the God King caught me off guard a bit because I was expecting something more like the Final Emperor. Whoops. Vivenna is probably the real show-stealer, though; she had a lot of character depth, and I really liked how the book explored her own strengths and weaknesses, and at times made you question which was which. Nobility vs. arrogance, idealism vs. pragmatism, her ability to judge characters and her being manipulated, etc.
I enjoyed reading Lightsong's chapters whenever they came about, and they were helpful for exploring the faith/gods theme, but their overall contribution to the story felt far less important. Lightsong himself at least is a sarcastic devil after my own heart.
Denth plot twist was terrific, totally caught me off guard. I called most of the other key plot twists (and a few which didn't happen). In hindsight I should have, but it was fairly masterfully done.
Didn't like Vasher at all. For a while he just feels like Kelsier mark 2 (pragmatic yet powerful magic user with a mysterious past), which isn't a good thing despite the fact that I like Kelsier. Late he gets quite insufferable as he just godmodes it up for the last arc of the book. Oh yeah he's also a genius scholar who already saved the world once and an amazing swordsman/awakener with a sword that kills anyone evil and oh yeah he has the perfect key to solving the Lifeless Army problem since he had a BETTER one all along! Whatthefuckever. (I'll grant that he did have a cool way to kill Denth, but still.) The whole scholars plot thread felt like a waste of space.
Pahn Kahl stuff in the ending really fell flat, too. I think for that to have worked, Sanderson needed to build up the Pahn Kahl/Bluefingers and their feelings towards Hallendren and Idris. As is it sort of felt like it came out of nowhere. Maybe a reread would help, there, but it's not a terribly convincing revenge plot regardless.
Book lacked a denouement almost entirely, which sucked. It's somewhat a product of the rushed ending - I felt a pang of worry when I was about 100 pages from the end and realised that this was a standalone novel, and this was pretty much borne out - but it's still frustrating. We literally never get to see King Dedelin again after the start of the book, which is a shame, and there was hardly any interaction between the two sisters after all that buildup. A bit of a waste.
Magic system was fairly uninteresting as far as actually using it for awakening went (and Sanderson seemed to realise this, he didn't use it much), although I liked its thelogical/sociological impact on the world and thought that was explored nicely.
I should probably track down Elantris at some point.
