Everything about this - especially Scott's name being absent from the "director" position - screams "bad idea." You have an original movie that was problematically based on a great novel... then you make a sequel with no basis in that or any subsequent novel?

The thing I wonder besides what Mikey wrote above, is does this srquel believe that Deckard is a replicant like Ridley Scott wanted, or is Deckard a human who learns that he is less human than the replicants he hunts, like Harrison Ford and Rutger Hauer wanted? Harrison Ford and Ridley Scott infamously fought over this movie. I assume human since Deckard ages, and also Harrison Ford would not come back for Star Wars unless they killed Han Solo. So I presume that Deckard would have to be human if they wanted Harrison Ford back.

Well, by the point of this movie he would have been long past the expected "shelf life" of replicants from his heyday. I had another thought: admittedly, this is just based on visual impressions, but the look of this seems to impose a lot more of the Mercerist philosophy from Dick's book onto Gosling's character. There is, however, no precedent in Dick's writings for this sequel. So; is this truly a written-for-film sequel to the 1982 film, is it an alternate interpretation based on one or the other viewpoints Nutso described, or is it an attempt at a truer interpretation of the book?
