If you like Big Sky Country and mysteries, this series seems like a perfect marriage of the two. It is worth watching for the scenery and rustic interiors alone. Based on a popular mystery series by Craig Johnson, the sheriff, Walt Longmire, is skillfully played as an independent, compassionate but tough lawman who is recovering from the death of his wife. Australian actor Robert Taylor plays this role but leaves his accent down under. At first he seemed nondescript to me. Couldn't pick him out in a line-up, but his magnetism grows on you. He has got an abrasive and occasionally annoying female deputy, Vic, whose impulsive energy is the perfect foil for his understated demeanor.
Series that are based on novels seems to have more depth of detail and nuances. Look forward to seeing future episodes. I think this is going to be a popular series as it has the essentials: likable detective, inspired casting, gorgeous setting, rustic western décor, complex plots and characters, and interesting dialogue.
