It's kind of what Superman has done since he was created. Go into strife filled areas and help.
Yeah, it's a trope because one of the key points of heroes is that they help out beyond the United States; and the truth is that many of the major conflicts in the world are in countries with huge amounts of poverty with even greater inequality than Europe and north of Mexico North America.
Not every movie can be as good as Rebel Moon or Army of the Dead.
I quite liked these films, but I've never seen their PG versions.
