From Community to House of Cosbys to Rick and Morty, Dan Harmon made a name for himself as a comedy genius. IDK much about Justin Rowland, but I assume he's at least partly responsible for some of the most brilliant moments of Rick and Morty, and I'm not just talking about the jokes. Among other episodes, The Wedding Squanchers, The Rickshank Redemption, Pickle Rick, Rickmancing the Stone and Look Who's Purging Now show great mastering of how action scenes are supposed to work. They ally irreverence, great rhythm and creative use of violence to make delicious gory spectacles. Unlike the increasingly incomprehensible movie brawls of today (I'm looking at you, Marvel...), their battles can be just as fast, but their choreographs are dramatic and easy to follow while retaining a great degree of complexity.
Dan Harmon and his team have a lot to teach to Hollywood.
