But I disagree that there was no character devlopement or fatal consequences in the MCU. There certainly was in Endgame. Why is the MCU any different from James Bond or the Indiana Jones movies or Harryhausen's Sinbad movies.
And Odin dies in Ragnorok and Asgard is destroyed.
I also find the fear that Superhero movies will dominate film the way they have comics meritless.
