Generally, I enjoy books for what books provide and movies for what movies provide. Adapting a medium that actively engages the reader and provides for things like asides, metaplots and complex arcs into a medium that requires visual cues and momentum can be a chore. Sometimes it's done well, sometimes notsomuch.
I try to keep an open mind and appreciate the story as presented in the medium.
That being said, if they mess up
Neuromancer I will demand blood.
