Blade Runner

Compared to the novel, the movie so far keeps up with the aspect of not being able to tell who's an android and who isn't. As of now, I'm enjoying the movie better because of the obvious visuals though the novel is far more descriptive in explaining all that unfolds. The overall setting in he movie  shows a dark future ahead and who's to say it can't happen over the next century and beyond with the increase in modern technology?
