Hmmm.... I do mind that they look the part so you can at least recognize them.
Avatar the last airbender movie was the worst offender of this,
because at least one cast member looked like another character from the show.

So the 1st one I have no issue with.

2nd needs a tan and spraying his hair to gray/white,
5th needed more red hair like this:

The 3rd and 4th ones look ridiculous though.

I don't know from which movies they are but
If #3 has an iconic beard, then #3 needs a beard and some better clothes if those clothes are iconic as well.
#4 is a no.

Can we be upset about all of them?

race is a social construct

I don't really care about this though tbf, most comic book heroes have multiple incarnations often with gender-swap and different ethnic groups, Ariel on the other hand is a character from a traditional European fairy tale. It bothers me more to see Tom Cruise as "the last samurai" than some random modern comic book character with slightly off skin color.
