I just enjoyed reading/Listening to the Hyperion Cantos for the first time. The first book, Hyperion was excellent, it in many ways sits in the Space Opera Genre. Its better to say its really a selection of short stories, as 7 travelers sit and talk about what brought them to the place they are, each tells a different story, providing a new perspective on the universe the Cantos is set in. Allowing you to see the old stories in a new light, and unraveling a small thread of the mystery you feel all though the book.
The Universe is fresh and original in many ways, and I can see how many of it elements quickly became tropes for other modern sci-fi.
