Great show.. I love the character Ray's darkness, And still a loving father. If you liked 'Breaking Bad' you'll love this type of series..
Favorite scene: Ray's at a carnival with his girlfriend and daughter. When some punk asks Ray if he has a problem?
Ray says " yeah mate you want one " and the look Ray gives this guy is Oscar worthy... we the audience knows the punk is close to his death wish... and Ray turns his back on him..
