Re: HBO's Boardwalk Empire
BE, Dexter, BB, GoT are ALL quality as far as I am concerned. But for me I'd say GoT is the show that's on another level. The Season 2, Blackwater episode is probably the best hour of TV I've ever seen in my life.
Current comic book TV show grades(ones that I watch, at least): Agents of Shield-[season 1: B-][season 2: B+]\The Flash-[season 1: B+/A-]\Arrow-[season 1: B+][season 2: B][season 3: C]\Agent Carter-[season 1: A-]\Daredevil-[season 1: A+]\iZombie-[season 1: A-]
