The creative elements in MCU films are (mostly) not director-driven, they are franchise-driven. You need a 'good' director and a 'good' script, with 'good' and 'famous' actors, from there, so long as the creative leads are professional and the budget is there, you're good.

I believe that DC suffers from bad creative direction and bad scripts. Most of the rest is workable.

Star Wars suffers from bad stories/scripts and Kathleen Kennedy interference politics.
