Enjoyed the first Hyperion, but Fall of Hyperion was a bit of a slog for me. If Fall of Hyperion were compressed into the conclusion of Hyperion and other stories left as novellas (in the way James S.A. Corey has done), I think I would have enjoyed the story more.
If The Fall of Hyperion were 1/3 of the length and part of the first book it would be perfect.
