Hollywood has ALWAYS stolen ideas and remade their own movies. It literally goes back to the beginning of the industry. Some of the most highly regarded movies in history are remakes. You like Charlton Heston’s Ben Hur? 3rd time that play based on a book got turned into a movie (the first time is actually one of the earliest movies made for release). Bogie’s Maltese Falcon? 3rd time in 10 years they filmed that novel.
In this instance Scott has never been satisfied with Blade Runner, he considers it one of his worst movies and has generally been visibly annoyed that it’s his best regarded. Probably his re-acquisition of the Alien (his other most highly regarded film) franchise probably made him think about finally doing Blade Runner “right”. Hopefully he won’t screw it up.
Maybe they have, but it’s epidemic now, and they have lost their skill.
The first whole generation of Disney movies was taken from Grimm's fairy tales and other older children's stories, sanitized by taking the violence out.
