Ok, this is all just my opinion.
Huge fan of Blade Runner, not so much of Do Androids Dream of Electric Sheep. I have to give credit where it is do though, Phillip K. Dick's writing has been translated into film probably more than any other science fiction writer.
I have mixed feelings on Ridley Scott, I have the directors cut (without Deckard's naration) and the original version. For me, the original version with the voiceover naration is perfection, something that Scott did not want to include originally. Since I am a Film Noirs fan and Blade Runner is Science fiction noirs, the voiceover naration is essential.
The tv series could be a real crap shoot as far as the final product. Hope for the best but be prepared to disavow...like Highlander.
