Back in 2005, when there was more of a distinction between theater movies and TV movies, longtime television star and second-tier cinematic leading man Tom Selleck began TV movie franchise based on Robert B. Parker’s detective novels. Although formulaic, “Jesse Stone: Stone Cold” benefits from Parker’s rich dialogue, as well as Viola Davis and Mimi Rogers in supporting roles. Selleck gets to play something familiar (a sleuth, this time as a small-town Massachusetts police chief) yet not (one with a drinking problem and a sordid past). It’s good, as far as TV movies go, back when there was a distinction.
