We must not be watching the same show. Because there is a clear story line combined with a whodunit. Maybe you just missed it. There is a lot of character development happening and to some that may come off as non cohesive. Mirren and Bronson’s characters are not the typical head of a mob a family characters and Harry doesn’t run a round guns a blazing which makes the show and it’s characters much more entertaining and unpredictable. They are only miscast if you have “Tony Soprano” blinders on. Love the show and love the characters. Best thing to hit the screen this year!!!!!
