I agree with you about how badly Hollywood butchers his stories. The the best one that actually tracked his story resonably well was Blade Runner. The short story was, Do androids dream of Electric Sheep?
Actually, Do Androids Dream of Electric Sheep was a full novel, not a short story. Also, the film and the novel differed greatly. The two written sequels to Blade Runner, authored by K.W. Jeter and authorized by the , stuck more closely to the screenplay and not to the novel upon which it was based.
