Unpopular opinion: RDJ is going to be a great Doom, and I’m happy that he is going to be able to still play a part in the MCU at this stage of his career. Dude is going to be wearing a mask, anyways. Also, Marvel has the opportunity here to make a star out of a younger actor playing Doom in flashbacks. All the “this scene doesn’t mean anything” or “universe is ruined” BS is so silly. The whole MCU as we know it was built on Iron Man’s back, in a cave, with scraps. Respect the art and legacy.
