I’m not sure as I don’t follow Marvel films, but I did always wonder if racism played a part in his criticism for Altered Carbon. Joel Kinnaman is basically the stereotypical Aryan alpha male actor (in appearance only, of course), so for him to be replaced by shorter black guy is exactly the type of casting choice that would trigger racists. And the second season wasn’t as good as the first, but the hate for Mackie was so bizarrely out of line with the okay performance he gave.
