Living beings can not be imprisoned, time can not be frozen

"The Petrified Forest" is the movie of the week. 

An isolated gas station in the arizona desert, the perfect place to stay petrified too.
A selfisn old man who holds his granddaughter working in the snack bar, a gifted young girl who dreams of a trip to France, a wanderer writer who lost the inspiration and discovers the girl's talent, a gangster waiting for his girl who betrayed him, a rich couple who finds out what's really important in life.

Living beings can not be imprisoned, time can not be frozen. Everything is moving from one place to another, from one situation to another. That's why the writer decides to die to give the young girl a possible future.

JG Ballard: his task was warning people

Global warming, consumerism, isolation, alienation, urban violence, he saw it coming. And I agree with him, science fiction is the literature of the 20th century. 
As a science fiction writer, his task was warning people. 
He didn't see himself as a pessimistic. His characters are in a quest and all of them accomplish something, whatever it may be.
