In a fairly surprising move, cable network A&E has opted to cancel its critically acclaimed drama series 'Longmire' after three seasons, despite it being the network's most watched show overall. This follows last year's cancellation of 'Longmire's former lead-in, Miami-set drama 'The Glades.' It would appear that A&E intends to scale back its original scripted programming efforts, with only a third season of 'Bates Motel' and the undead drama 'The Returned' on its scripted slate for 2015. Production studio Warner Horizon now plans to shop the series to other channels.
