This reminds me of the discussion of the new cast for the Harry Potter HBO series. They get so much hate online (how sad your life is when you attack child actors online) because they look so different from the OG crew - but honestly they look much more like I imagined them in the books, especially the foto of the Harry Potter actor in costume.
I also never have a problem with changing actors, its just a different interpretation of an artist, its a different perspective on the content. But I also have no problems with remixes and covers of songs, often I even like it to hear new takes on old favorite song of mines. (What I don't like are cheap moneygrabbing EDM remixes with a bassline you heard 1000x times).
As long as the quality is good, yes please change actors, directors, artists, musicians, I don't mind, show me all the facets the cultural world has to offer, I'll give it a chance and I don't understand people who are so fixated on it. But on the other hand I don't understand the whole MCU hype in general not really and I am glad that its seems to be on decline and maybe stop holding contemporal pop culture in a stranglehold.
