I specifically said it is a problem for me, not for you.
I don’t care about Dumbledore because I didn’t realise. That analysis is very subjective and exactly why I said these thoughts apply to me.
Forgot about the Dark Knight. Annoying, and that should be fixed.
I also said to me they are plotholes. They’re probably not.
Tony Stark doesn’t look like RDJ in the comics because it is a different universe.
And your solution (pretending there was no change) doesn’t work for me but probably for most.
This is also why I called my idea stupid.
As for younger characters, I would like the younger characters to look like how the actors actually looked when they were younger. To me, it is not as important, so I focus more on casting changes during the same age.
I hope you understand this is merely my point of view.
