I like Blade Runner. I don't love it. I've always felt this way. When I saw it, I didn't know about the novella. Then I got into PKD in a big way (he's in my top 3 favorite writers) and I read almost all of Androids without realizing it was Blade Runner. They are so far removed from each other, it is almost not an adaptation.
Of course, you can say the same thing about Total Recall & We Can Remember It For You Wholesale... But (IMO) Verhoeven added a lot to the source material while retaining the best parts of the short story. This is easier to do (obviously) when adapting a short rather than a novella, especially when you're talking about writers like PKD... And, to be completely transparent: I love Verhoeven.
Yeah, adaptations of beloved books are often hard to stomach. My problem with Blade Runner is different though. It's super stylish, but it's also a bit bland.
Harrison Ford described Deckard as boring and he's not wrong.
The protag in Androids is a complicated individual. He's married and he uses a machine that distributes drugs according to mood. There is almost nothing left of that character in BR.
Both Kubrick and King made different masterpieces with their respective interpretations of The Shining, but it's still the same story more or less. It's still Jack and his wife and son going to an empty hotel in the middle of nowhere.
Stephen King didn't like Kubrick's version.
I'm not convinced PKD would have loved Blade Runner.
