A couple things
1st
The exposure of the most significant Tower witch, besides Egwene herself (not telling who for those who haven't read yet), as a darkfriend read like the script of an episode of LAw and Order
Not sure who you're calling the "most significant tower witch" but if it's who I think it is there was never any mention of her actually being a DF
2nd
If Brandon can ask Ludlum about psychological thrillers than I'll be VERY impressed, as he is VERY deceased. (

3rd
...instead it read like an really bad tantrum, and the narrator was as bored and unfocused as the reader.
This is an opinion stated as fact, I for one was not bored and unfocused.
There are some areas that could use a little work, I wasn't a big fan of the opening chapter, but was not completely turned off by it. I loved the Prologue, and felt there were a few people who were a little 'off' (mainly Mat and Tomanes). These did not ruin my enjoyment.
Remember Brandon sat down to write each POV from where they were to the beginning of the last battle. There is bound to be some continutity/timeline confusion when doing this. I'm sure ToM will help get us on the same page to gear up for the last battle.
Brandon has the foremost living experts on the WoT helping him complete the series. While the voice is most certainly different (it should be, he's not RJ. That is not a knock, I would say the same if RJ were alive and finishing up Mistborn for Brandon) if it read like a Bourne book I would feel very cheated (I LOVED the original Bourne books)
