Ok, technically this one isn't wholly original, as it had aired before Netflix, but it still counts as Netflix have since produced their own original episodes, and are going to continue to do so in 2016. Longmire, based on the Walt Longmire Mysteries series of novels by Craig Johnson, aired its first three seasons on A&E, before the network decided not to renew it. Netflix came in and saved the show, with Season 4 airing last year. It wasn't just a one-off swansong, and Robert Taylor's Wyoming sheriff will get to pick up on the events of last year when Season 5 rolls around.
