Read the first book of a planned ten book series??
No thanks, I'll wait until seven or eight of them are available before I even think about reading the first one.
From what I have read, Sanderson appears to be a micro-manager when it comes to world-building... he wants to spoon-feed me each little detail about his world - just in case I should misinterpret and get it wrong, I guess. I prefer to use my own imagination.
He's not alone in this. Many fantasy authors tend to not trust their reader's imaginations enough. The world-
building is my job as a reader. I just need a few world-
hints to to get the ball rolling.
He's certainly prolific - I'll give him that. But, I'll be very curious to see if he can keep up the aggressive publishing pace he has set for himself.
