It had to end sometime.
Even though the series outlived Robert Jordan, and was passed to Brandon Sanderson, we all knew that it would be ending. It's a testament to Sanderson and Jordan both that, in retrospect, it seems inevitable that this would be a great book. This book has the benefit of 13 books to set the stage, but it also comes with all of the expectation of those 13 books. It takes a great grasp of character to make all these storylines feel complete. Sanderson and Jordan nailed it.
Though I am sad to see this series end, I couldn't have asked for a better conclusion to this series. This serves as a worthy capstone to the best epic fantasy series ever.
