The series has so many unique elements that all work in very unpredictable ways. You really can't fully expect anything from anyone. One repeating complaint that I have noticed, and which I could partly sign myself, is that pretty much every character often goes through this philosophical monolog that some people may find tedious and ponderous. Sometimes it slows things down, but you may get used to it and start to enjoy it after awhile, as I did.
I also appreciate the merciless manner in which Erikson cultivates clues that can be resolved thousands of pages later. And BTW, this is probably the only series for me that has been better as a reread. Erikson has this great skill to generate characters that are full of mysticism and epic-ass coolness. Once in a while, these characters encounter in an earth shattering way, or in a way that makes your brain hurt from thinking about all the possible plot derivates. And foremostly, the world feels alive because everything seems to affect everything, sometimes it's prominent and sometimes it's something minor, but it's always there.
I like this series so much that I have started to distance myself from it to give other books and series a chance. It really has become the thing to which I compare every other fantasy book in my life.
