I can honestly say that I haven't seen any shows from America that are serious. They base their whole show on comedy. I mean some of it is actually funny, but I'm getting tired of it. In anime, there is a huge amount of serious shows. Even in things like Pokemon, they take their adventure seriously and don't waste every second of the show for comedy. But in lets say Teen Titans Go, there is no heroic acts. Just some comedy.
So have you seen any shows from America that are, for the most part, serious?
