Keep going, it is a bit of a slow starter. The characters need a bit of time to show their colours and the relationships are a little difficult at first (or at least they were for me.)
Agreed with True Detective - it was an awesome bit of television.
Absolutely love House of Cards. The set up for Season 3 (which starts soon) is unbelievably good. I have it up there with some of the best TV ever made.
OITNB is a lot of fun as well.
