I think this was fine. It did what it set out to do, and it did it well. The humour is very Sanderson, not my favourite but really works for some. The continued world-building was the best part of this book. Not sure I'm going to continue the series though, at least not right now. I didn't go in expecting a continuation of Mistborn, so I'm not disappointed. Just not in the mood for something this fast-paced, or something 'funny'.
