19DISAPPOINTED: HELMUT ZEMO
In Marvel comics, Baron Zemo is often seen wearing a purple mask and plotting to get revenge on Captain America. Helmut Zemo, the 13th Baron, was featured as the main antagonist in Captain America: Civil War, and boy was he a disappointment. Daniel Brühl is a fine actor, but there was not
much he could do with such a small role.
In the film, Zemo is merely a man who is playing the long game in pitting the Avengers against one another. While there happens to be a fairly good twist near the end involving the creation of other super soldiers, this version of Zemo just has no staying power. He is given a tragic backstory, but other than that, the characterization is weak. Maybe it would have been too much in a story where the superheroes are fighting each other instead of the villain.
