My parents like MCU quite a lot, but they only saw the movies (and not all of them). They were honestly quite lost while watchiing endgame (because of the number of characters)
Man, I cannot wait for the moment some movie does catch their eye, and I will have to explain to them, that they missed WandaVision, The Falcon and the Winter Soldier, Loki, What If, Hawkeye, Moon Knight, Ms. Marvel, She-Hulk and Echo
