It is popular opinion that the movie Blade Runner was altogether better than the novel on which it was based, Philip K. Dick's 'Do Androids Dream Of Electric Sheep'. Quite frankly, having read the book before seeing the movie, it seemed quite disappointing to me, when compared with the original. The importance more interesting, philosophical subjects of the novel was cut down meaningfuly; namely, the philosophical consequences of the idea of a humanoid robot that would be superior to man himself in any way. J.R Isidore (transformed into the very minor character of J.F Sebastian), Buster Friendly, Rick's wife and her eery mood-dialer, and most of all the electric sheep, the most wonderful symbolism in the novel. These were all removed. The idea of the artifiacial animals was only hinted, as was the unsolved question of whether Deckard himself is a replicant or not. But IN SPITE OF ALL THAT -- when considered individually by its own right, as it should be (it's no accident that the film and the novel have different names!) Blade Runner is still one of the masterpieces of sci-fi cinema. Harrison Ford - though he plays the exact same character he always does - fits right in. Ridley Scott's directing is superb. His biggest stroke of genius is in his relating to a theme that was very subtle and weak in the novel - the film noir atmosphere. Scott did an incredible job creating a futuristic classic film noir, right down to the electronic-film noir musical score. As an action and an atmosphere movie, Blade Runner is one of the best sci-fi films ever made. Highly recommended for all fans of the genre. Reading the novel is completely unnecessary to appreciate the film.
