I was already aware that the movie was drastically different from the books, but I didn't realize just how much! Apparently I'm going to have to add this book(s) to my reading list.
I've tended to avoid most robot based sci-fi for the same reason Asimov apparently wrote the series of shorts, it's really annoying to have every sci-fi with robots be a dystopia of how everything goes horribly wrong because of people's over reliance on technology. Because god forbid technology ever be a good thing. All technology is clearly evil. Medicine, buildings, tools, heating, air conditioning, and refrigerators don't count somehow.
It is more difficult to write a story where people use technology for GOOD, but hell, that just means that all these stories where technology goes wrong are lazy :p
