I read Hyperion recently and I think it would suffer from movie treatment. Like McCarthy’s The Road, so much of the horror in Hyperion comes from what is left to the imagination, like the terror of the shrike; and that which is internal to the characters, like the pain of the cross.
I doubt these could be translated effectively to a visual medium.
But other scenes, like the squishing of the literary agent between the floor and ceiling of a building that had been, up until that moment, supported but some kind of energy field, would be spectacular.
But more generally I completely agree with your comment. I also think the religious symbolism, like the cruciform parasite and the tree of pain, were a bit cheesy and overwrought in the writing, and would come across cheesy in a film, too.
