Just thinking why mcu simply changed kang to doom instead of changing the actor( jonathan majors). It's like skipping the introduction of X-Men and fantastic four bringing them to the main story and event's ( the Avengers thing) .

Before avengers : endgame i used to have a Facebook and Ironman fan club, after watching Avengers endgame I couldn't accept Ironman death it trolled me so much that I uninstalled my Facebook and still after six years I don't have facebook and yet I continued watching mcu movies . That's how avengers endgame effected me .
