IMDB’s Description
In a dystopian future, Joseph Dredd, the most famous Judge (a police officer with instant field judiciary powers), is convicted for a crime he did not commit and must face his murderous counterpart.
The exposition states that the Earth has become a wasteland and the people live in Mega-Cities. Crime is rampant, so the people create a police force known as Judges who can try, convict, and execute at their whim.
Then the movie opens to Rob Schneider, which is never a good sign. A recently released convict out on parole, Schneider gapes at the city and the scenes before him, as if he didn’t live in this city before serving his two year sentence. He must be a pretty stupid guy too, because he believes a rooftop paradise is his new court appointed living space. He arrives at his actual apartment to discover it is occupied by a gang of squatters. Then a street war breaks out and the entire block is engaged in a firefight.
