Imho, it's a toss up between Tom and Donnie for the best character. But if you enjoy Tom as a soft spoken "top cop" you need to find, and watch, the "Jesse Stone" series. All 9 of them:
Jesse Stone: Stone Cold (2005)
Jesse Stone: Night Passage (2006)
- a prequel to Stone Cold
Tom Selleck plays the Chief of Police in a sleepy coastal town called Paradise, Massachusetts.
But they have crime. Murder, Drugs, Domestic violence... you name it - they got it.
All the while, the Chief, who insists that people call him just "Jesse," deals with it, and a new divorce from the woman hw still loves, and a severe drinking problem all at the sam time.
