Which old science fiction books are considered the best?

For me, 'Ringworld' by Larry Niven is among the best. It has a really unique and imaginative concept of a huge, artificial ring in space. 'Childhood's End' by Arthur C. Clarke is also a top choice. It deals with the arrival of an alien race and the transformation of humanity. And 'The Time Machine' by H.G. Wells, which is an early and very influential work. It makes you think about time and the future of the human race.

Definitely 'The Andromeda Strain' by Michael Crichton. It has an alien - like microbe from outer space that causes a major crisis on Earth. It's a page - turner. 'Rendezvous with Rama' by Arthur C. Clarke is another great one. The discovery of the huge alien spacecraft Rama is fascinating. 'The Left Hand of Darkness' by Ursula K. Le Guin has a unique alien race, the Gethenians, whose gender - less nature challenges human concepts.

One of the best is 'Hyperion' by Dan Simmons. It has a complex structure and a richly imagined universe. The different stories of the pilgrims on their way to the Time Tombs are really engaging. 'I, Robot' by Isaac Asimov is also a classic. It introduced the Three Laws of Robotics, which have been a staple in science - fiction discussions about artificial intelligence. And 'Fahrenheit 451' by Ray Bradbury, while often seen as a dystopian novel, has strong science - fiction elements in its vision of a future society that burns books.

I think 'The Time Machine' by H.G. Wells is quite good. It shows different future societies, one of which could be considered a utopia in some ways, with the Eloi living in a seemingly idyllic but ultimately flawed world. Another is 'The Left Hand of Darkness' by Ursula K. Le Guin. It explores genderless society concepts which are related to creating a more inclusive and perhaps utopian social structure. 'Solaris' by Stanislaw Lem also has elements that make you think about utopian ideals in relation to an alien planet and the human attempts to understand it.

In my opinion, 'Ender's Game' by Orson Scott Card is one of the best in science fiction books. It delves deep into the mind of a child prodigy, Ender Wiggin, who is trained to fight in a future war against an alien race. The book explores themes of morality, leadership, and the cost of war. Also, 'Brave New World' by Aldous Huxley is a classic. It presents a future society where people are genetically engineered and conditioned to fit into a specific caste system, making us question the price of a so - called 'perfect' society.

I think 'Star Wars: Expanded Universe' books (now known as 'Star Wars Legends') are great. They expand the already vast Star Wars universe with many different storylines, characters, and planets. It gives fans a deeper look into the lore behind the movies.

For me, '1984' by George Orwell is a top choice. It's a dystopian novel that warns about the dangers of totalitarianism. The concepts in this book are still relevant today, and it makes you think about privacy, freedom, and the power of the state.

Among the best in 2016 fiction are 'LaRose' which is a very emotional and deep story about two families. 'The Vegetarian' is quite unique. It's not just about a diet choice but about a woman's inner struggle and her relationship with the world. 'Commonwealth' is also excellent as it shows how one event can have a ripple effect on multiple lives over time.

Definitely 'Sense8'. This show has an amazing concept of eight people from different parts of the world who are psychically linked. It has elements of science fiction in how it explores this connection, along with great action scenes, diverse characters, and a story that promotes unity and acceptance.

Well, that's a matter of personal opinion. Some might think 'Star Wars' is the best because of its epic story and memorable characters. Others might prefer 'The Matrix' for its innovative concepts and action scenes.
