Dick never saw the film. In fact he died before it wrapped. He loved the dailies Scott showed him because he felt they captured the feel of the novel very well and he was supportive. He also said he thought Sean Young was perfectly cast. I'd be surprised if he would have been happy with the finished product. It just wasn't his style to accept other people's interpretations of his work. He was very critical of Ursula Le Guin on that point. She OTOH was incredibly supportive of him, calling him "our own home grown Borges." Dick also had a big fight with the studio because they wanted him to write a novelization of the film.
