The Knick - I am a sucker for period pieces, and Clive Owen is incredible. The 1901 medical tech is fascinating, too.
The Returned (Les Revenants) - French fantasy series based on the film of the same name from 2004 about the effects on a small town when the previously deceased begin showing up, unaware that they've passed. This is IMHO among the best television series of the past decade.
In The Flesh - Post-zombie apocalypse drama set in a world where the undead can be reformed by medication into 'Partially Deceased Persons' and re-integrated into society. There are two series and only nine episodes in total, so it's not a huge investment, but so worth it.
Broadchurch - David Tennant is a harried DI set to find the killer of a boy in a small seaside town. Less about the cop stuff and more about the effect of the murder on the small, tight-knit community, I binged the first season in a couple of days. It was remade in the US as Gracepoint, but for the love of god avoid that and go to the UK original.
