All of these characters feel rushed, things that they've become comfortable with are turning on their heads. We feel that in reading it. That's one of the things that I enjoy about Brandon's style as it's grown, when you read a character's POV, you can almost feel their state of mind.
It's also important to note that the editing team sees a much bigger portion in a shorter amount of time. So getting spoon-fed a couple chapters at a time is a much different experience than just sitting with the book, and knowing the whole picture also makes a difference. And I assure you, when people dislike something, they speak up about it, quite freely.
I would agree that day 1 is probably the weakest, but the book is overall amazing. This is just that weird catch 22 of getting some preview chapters.
