Longmire & H e l l on Wheels are my 2 favorites. Narcos is a good watch but pretty violent. Stranger Things is entertaining as well, I like the 1980's setting of the show. Might have to look into Dexter.
I watched that one to, that tall nut case character with the irish accent, the one that finally got hung at the end, made me want to hang him myself, thats how good an actor he was. I also liked the Bow Hannon actor.
