The BOOK Me, Robot.
The book Martian Chronicles
Star Wars was great as regards adventure, but to me real sci-fi is the one that makes you think what's the point of so much progress and technology if man does not try to progress himself, showing all our weaknesses.
There are many Sci-Fi's I like but I do not consider the best, just entertaining:
- Jurasik Park
- Men in Black
- Star Wars
- Allien
- Terminator
and the like. But stories such as the real Me, Robot a and Martian Chronicles try to study the way we are, not just showing a nice sci-fi story.
