It's pretty simple really, it's easier/safer to portray a villain in that way than as any stereotype based on a nationality.I just returned from seeing it. IT was awesome. The most lighthearted and funnier Marvel movie yet.
Id say its a combination of Guardians of the Galaxy comedy style with Iron man.
Not to mention the introduction of a few ideas for next movies.
Specially loved the reveal in the after-credits scene.
The only bad?
I REALLY HATE THAT DUMB "I'm a badass CEO WOMAN" haircut.
We seen it in Jurassic World, now on Ant Man.
Also..Marvel really loves to portray the bad guys as BALD business men.
I mean, Iron Man's excellent Jeff Bridgeas as Obadiah Stane.. then another bald one on the third movie in the fake Mandarin.
We see a Balding CEO again with YellowJacket.
And pretty sure we seen some lesser villain commanders that are bald(in other marvel movies, like in the new avengers).
also loved the Wasp references.
