Haven't seen the move yet but all of the negative fan reviews make me think that the magic sauce to the MCU is the Russo brothers as directors. They've directed pretty much all of Marvel's heavy hitters (Cap II and III, Avengers III and IV) sans Black Panther (Ryan Coogler). Should I panic now that the Russo brothers, AFAIK, are not signed on for any Marvel movies after Avengers IV?
