New input case for you: 50,000 years in the future and they are still smoking cigarettes, reading newspapers, the main power source is nuclear energy..and they carry nuclear guns??? A kid in the 2nd grade has more imagination!I almost made it to the end. It had gotten so absurd that it finally just drifted off to a shelf....What I didn't like:1) Lack of imagination (see above).2) Cardboard characters. Nobody to really cheer for..either the character is a pencil necked geek or some babbling fool.3) False religion mumbo jumbo: never would of worked IF most/allthe priests new it was a farce.Avoid unless you need something to stoke the fire with next winter.
Output:
Negative
