I watched the movie "The Hitchhikers Guide to the Galaxy".
It is SF as a genre, one part regarding science , but as a whole, the work is full of the social satire in the context of SF.
Just a little, it is the news item being discovered, but
The reason why the earth is destroyed is "construction of the hyperspatial express route", but that has been "on display in your local planning department of the Alpha Centauri for 50 years". Naming "public announcement" in front of the government office, many documents which have too small letter posted. It is severe sarcasm to government officers way of work which " take something fully informed to the people by such way of informing" .
There is the "nutrition beverage automatic synthetic machine". Inspecting the body of the person who pushes the button, you say that it synthesizes the beverage which is really in need, but to tell the truth the machine always makes up the same ones, furthermore that is unpalatable. This is the satire to the mass consumption society which tries to make everyone buy the same ones, while doing the advertisement that "very this it is something what you need". Furthermore, the conclusion "what in need are never obtained", it is full of sarcasm.
There is a work, "Gulliver's Travels (Jonathan Swift)". Normally, it is regarded as a juvenile novels, you may read the story called "The dwarf's country" in the time of the childhood. But as for the original it is rather a nonsense fiction, full of satire to the society of that time. Unique sense of sarcasm, British people has. You could think "The hitchhiker's guide to the Galaxy" , as the work which succeeds after "Gulliver's Travels".
