This is a tough one for a reason that is so obvious it's barely worth stating, but what the hell - a film and a literary work are fundamentally different! Ridley Scott's Bladerunner and the novel by Philip K. Dick on which it is based, Do Androids Dream of Electric Sheep, aptly demonstrate the issue. Both are excellent in their own right, but if we judge the movie on the basis of the novel where does that leave us?
