This movie is textbook example of Human Supremacism and lack of diversity :-(
Thanos has been destroying numerous alien civilizations, but when it comes to save the day, guess what? It's all about HUMANS. Humans and humans.
The lack of diversity in this movie is extremely disturbing. Non-human alien races has been historically discriminated and hidden in movies, a common trait in the mainstream planet Earth's human supremacism. Who beat Thanos? humans! Who beat Galactus? humans!!
It's sad and offensive how human supremacism is the mainstream ideology in planet Earth. It dismisses and discriminates non-human races, oppressing them and considering them as inferior, not worthy enough to be represented in a movie. Instead of having a movie that represents the wonderful galactic races diversity beating Thanos, we have this xenophobic human-centered view filled with hate towards human and non-human diversity.
There's a glass ceiling in Marvel movies for non-human characters while humans like Brie Larson use their privileged position to represent xenophobic heros. And it's time for humans like Larson to step back, apologize for their human supremacism, and let the galactic diversity enter the Marvel Universe.
