I really enjoyed Fall of Hyperion. It's very different from Hyperion, but I think the plot is still very satisfying. Endymion and Rise of Endymion are okay and interesting in their own way, but a definite step down IMO.
It is different, and it does wrap up the quest at least. I guess I read it quite a while back and thought of Hyperion and Fall as one book in two parts, and got carried away in my original comment.
