Finished it Tuesday night, although I'd like to give the latter half of the book a more in depth re-read.
Overall, I was quite satisfied. The ending was great, and perfect for what Jordan intended from the get-go. While I have some minor quibbles with how some scenes played out, and the lack of some POVs that I would like to have seen, the major story beats were spot on. Rand's conflict with the Dark One was very well done, and the last scene was perfect.
Below are some of my thoughts on the how the book ended. It does not contain any actual plot spoilers, but is more about the way in which the book ended. Still, if you really want to experience the book without knowing anything about how it resolves, read no further.
A lot of people will deeply dislike how this book ends, not because of anything that happens, but because of what doesn't happen. Don't expect a drawn-out ending, a la, the Lord of the Rings trilogy, or even a "20 years later" ending like in the Harry Potter books. A lot of questions are going to remain unanswered, but thematically this fits well within the world that Jordan created. This isn't the ending, only an ending.
