Since I've already mentioned that movie here , it is one of the few movies (based on a novel . .) which more or less tells the truth about television-control . . . .
It is dytopic though . . . In the plot a totalitarian state is in place , television more or less rules completely and 'delinquents' are punished severely . . . .
. . for the 'amusement' of the masses .
The guy who wrote the novel was Stephen King under the code name Richard Bachman .
