I don't know what they might be upset about if the Russkies and SoKo's actually saw the movie. The film "Captain America" is, according to its director, not very patriotic at all and has little to do with America:

"He wants to serve his country, but he's not this sort of jingoistic American flag-waver," Johnston told Hero Complex. "He's just a good person. We make a point of that in the script: Don't change who you are once you go from Steve Rogers to this super-soldier; you have to stay who you are inside, that's really what's important more than your strength and everything. It'll be interesting and fun to put a different spin on the character and one that the fans are really going to appreciate ... the idea that this is not about America so much as it is about the spirit of doing the right thing," the director said. "It's an international cast and an international story. It's about what makes America great and what make the rest of the world great too."
