Not so great things: What is up with Marvel and the villain of the week? Besides Thanos, who has really only been vaguely featured in Guardians, and Loki (who is now a fan fav), why can't any villains survive and show up again?
How fantastically fun was Killmonger? Why couldn't he live to pester our heroes another day? And did Marvel seriously not want to give Michael B. Jordan a chance to return in the future? This isn't just a problem with Black Panther though, it shows up in most Marvel movies. While I don't want Marvel to go into Batman territory (seriously Batman, how many lives would you save by just killing the Joker instead of sending him to jail time and again? Though I can't just blame Batman for that, that is most comics). But would it really kill Marvel to have a few villains escape to fight another day?
