The main character, Frank Perry - is nuanced and complicated, but Ross Kemp does a fine job in portraying this character.
Frank Perry made a bad decision a while back in his life and has paid for it ever since - until the one day he decides to put a stop to it. He then draws a line in the sand and faces his enemies. Gripping drama - my only complaint is that it is too short. I would have liked to see this as a mini-series rather than one short movie.
