This hollow if AND perversely UNwatchable exercise in self-annihilation builds to a violent finale that finally makes good on the biopic's sordid potential, as Trank shoots his way out of oblivion with a sequence in which Capone does the same. It's a climax that manages to blur the line between truth and legend, and to clarify Trank's ambition of making a movie about how one tends to infect the other.
