I absolutely loved this book. It was exhausting, rewarding and absolutely epic. Of course I do have some misgivings, I know some people believed too many characters met their ends, but I have the opposite opinion, I was absolutely convinced that one of the ta'veren boys had to die, that all three came close just to spring back miraculously seemed to make light of the gravity of the situation. The other thing was the zero build up of Fain's end battle with Mat, of course it's been foreshadowed enough through out the series but there was nothing in the book to suggest Fain was even active until he sprang onto the scene with a new name. But really these things do not bother me overly much and with further re-reads I will definitely come to see why it ended up like this.
The very ending itself I thought was perfect, just open enough to let the world breath (and the theory boards still rolling) but final enough to bring closure. Amazing end to an amazing ride.
