I really have a big question about this movie.

Is Africa a country? Do Africans share same culture even if they are from different countries and might hate each other in the history?

Definately no.

But Killmonger, who grew up in the US, seemed not understand that and not really respect African diversity and Wakanda culture. Himself may suffer from discrimination in the US. But there is no reason for him to ask Wakanda people to fight for all of African. He just supposed that Africa is one entity.

It's wired.

Will Amercians fight for Candians/British or share their tech just because they are all white people? All live in the same continent? Or share the same ancestor?

Will Japanese people fight for Koreans and forget the war history between them? Will Vietnamese save China during crisis? These are all asian countries. Maybe Hollywood is too arrogant to distinguish them, but these cultures are quite different. They will never stand together only because of skin color or they are asians.

Killmonger just ignore this huge difference and so did Marvel. The film just depicted a Hollywood Africa again. People live in love and peace. People will help strangers only because their skin color. (Since Wakanda is so developed, it seems impossible to catch them as slaves. So they really have no reason to help other African people other than color.)

When you make a film of other culture and did not really think about about it, you get Black Panther. This movie does not really respect African countries.

Disappointing. I hope Marvel would show some real diversity.
