I beg to disagree. (about not ending the book at the death of Turin)

As I think I've already said, I found the epilogue extremely effective and imo, including Hurin and Morwen after the death of the children was vital.
The book is not called Turin Turambar. It is called the Children of Hurin. They were cursed because Morgoth hated Hurin. Hurin on the high seat, forced to watch the utter effectiveness of the curse on his family - that is a fundamental basis of the story.
Any normally inquisitive reader would want to know, what happened to Hurin, did he die on that chair, or what? So the epilogue is vital. And I would have liked more, at least in the appendix if not in the novel itself. The passage just posted by Maedhros, for example.
