Because Adrien Brody is superb in this movie! Brody plays a writer/investigator for a tabloid publication and he finds himself entwined into a complex mix of thugs, power brokers, prostitution, and murder. Himself and his family become endangered by his investigation but he cannot give up on the clues he uncovers to solve a mysterious murder.
This movie has a particular feel and look to it. Director/writer: Brian DeCubellis has created a film that has his signature on it ... in other words this is his movie. You feel the deceit, the lust, the grim, and ambition in each character. At two hours long some people may loose patients with this story but it's all worth it for the ending because the ending puts a finality to the murder mystery but a new emotional mystery is left unended.
If you like complex mysteries with numerous dead ends for the investigator but the investigator can't give up this is a good choice!
