We’re sort of comparing apples to other apples here, and I’d have to guess the other Infinity War actors aren’t displeased about Chadwick Boseman and co.’s success (at least I’d hope).
At the end of the day, though, it’s somewhat in poor taste to be like, “Hey Avengers, here’s your consolation prize.”
After all, Infinity War had a shocking ending, made great use of an ensemble cast, told a superhero story we’d never seen before and let the bad guy win.
