Having watched only halfway through - ep. 5. I thought it would end there, but it seems there's more episodes. I've enjoyed this, but the plot/mystery is not too surprising or unpredictable if you've watched a few Scandi noir series (and I stand guilty as charged). The interaction between characters was what made it for me, particularly the relations between FBI agents and local police.
I like Carrie Anne Moss and it's always great to see her in non-American productions (like her role in the second season of Channel 4's Humans). A bit disappointed about the way John's character was handled by the writers though. I thought they would play with the race theme much more than they did, but that hardly happened. Basically his character (a) had sex and (b) messed things up. If they chose to cast a black actor in order to deal with racism, they seem to have only reproduced stereotypes themselves.
