Query: Dark and mysterious

This is Ray Liotta and Jason Patrics' best movies in years. They act their parts wonderfully with the darkness that fits "Narc". This is one of those movies that keeps you thinking about the truth for the whole movie. You think you know what's going on, but you always learn otherwise. That is what makes a great movie. However, "Narc" didn't receive enough recognition, only grossing in the seven-digits dollars. If you're looking for something unique and dark, rent this one. You won't be disappointed.
