Crusading. Alone.

"Knight Rider, a shadowy flight into the dangerous world of a man who does not exist. Michael Knight, a young loner on a crusade to champion the cause of the innocent, the helpless, the powerless in a world of criminals who operate above the law. One man can make a difference: Michael Knight, a lone crusader in a dangerous world... the world of the Knight Rider."

How many people heard this preamble? Now just realize its utter stupidity.
First of all, Michael Knight is a "loner on a crusade" and a "lone crusader"! Thesauri are made for a reason, people. Equally stressed is his living in a "dangerous world" (twice), although he is rarely in any mortal danger.
My favorite, however, are the " criminals who operate above the law." Don't confuse them with law-abiding criminals.
