Did the fact there was hardly any real Nazis in this film hurt it? I think so, if you look at Captain America comics from the 40s he spent most of his time fighting Nazis. Red Skull was created as a Nazi villain, he was second in command in Nazi Germany in the Marvel Universe. Red Skull being associated with the real world evil of the Nazis is part of what made him such a vile and sinister villain. Hydra just doesn't pack the same punch the Nazis do. The Nazis are iconic symbols of evil in the modern world, I don't think Hydra can make the same claim. Red Skull not being associated with the Nazis makes him less evil and sinister, it makes him kinda generic. I think the movie would have better if it was a straight Cap vs. Nazis film.
