"Do Androids Dream of Electric Sheep" vs "Blade Runner"
The book is strange, but I suppose everything by Phillip K. Dick is. The characters had such goofy dialogue. I must confess I never really understood the significance of Mercerism. I suppose the point of the book was that the only true human element is empathy... empathy for all living (and non-living)things.
The movie was one of the greatest movies in movie history, but I think you have to read the book first in order to realize what is going on. It's strange how the story is so different than that of the book, however. Why did they make Rick Deckard an android in the movie? Did it make the story any better?
My favorite movie quote of all times is, and I'm typing this from memory, "... all those moments will be lost in time, like tears in rain."
