(Posting my thoughts in a second post to avoid tooltip spoilers.)
I liked it a lot. It was a good, worthy ending for the series. Sure there's bits and pieces that could be nitpicked, but I think the emotional arc was true.
One thing I really liked was that the villains were worthy villains. The plan with the four great generals was outstanding, as was Demandred. And Lanfear's plan at the very end.
