All of the cursing, explosions, blood and bullets lead to what can only be described as the only human moment in the movie--Chev Chelios' touching last phone call as he falls from a helicopter before landing in a parked car deathbounce.
Technically, there is no point to the story. Chelios was hired to kill a crime lord and is then double crossed by his employer. But at the end of the film, we learn that he never did kill the crime lord, and Chelios uses his "spared hit's" backup to bring about the absolutely spastic concluding firefight.
This film is a cacophony of teenage video game angst. When I say "video game," I am tapping into the truth of the whole concept. Video games are referenced constantly. Chelios tells his girlfriend that he is not a video game designer but a contract killer. The symbol for the men's room looks more like a character from STERN'S classic game BERZERK. As a matter of fact, one of the many dispatched henchmen in the game is seen playing BERZERK in the back of an armored Hummer.
CRANK 1 is definitely a fecal trumpet blast announcing the end of Western Civilization as we know it. There is no question that our society is doomed. I just hope I get to see CRANK 2 before we are all cast into darkness.
