Earlier quoted context omitted.
I'd rather have the obsession everyone has for the few remaining animals on earth, and the race to own at least a replica. Electric sheep are just a background detail in the movie, while they're as central as hunting the replicants in the book... I'd also like the scene where Deckard runs into another blade runner agency, further complicating the question if he's a replicant or not :)
Yeah, the film could have had more content about the real/artificial animals though it did feature a bit with the snake scales and the owl. Also agree about meeting the other agency though I can imagine that would have complicated the plot a bit (disclaimer - I haven't read Androids for many years and can't remember the details of that scene). I just think that Mercerism was a superb concept - a participatory religio…
Deckard gets arrested by a different police agency - they think they're the only ones, just like Deckard's agency. He gets accused of being an android with implanted memories.
They administer Voigt-Kampf tests to each other and while everyone ends up as human, the scene serves to make who's human and who isn't even more of a question.
What really ticks me off about all movies made from Dick's writings is that they cut off most of the ambiguity.
I shudder to think what they'd make of Ubik or A Maze of Death...
