Mark Millar is one of the top comic book writers in the world. He wrote the original "Captain America: Civil War" comic book series. So, what did he think of the Captain America: Civil War movie? He didn't like it. Millar's issue with the movie is that it did not feature the light as well as the shade" in the form of comic relief moments. "'I really hope this bleakness doesn't extend into their two 'Avengers' pictures because what made that first 'Avengers' work was the light as well as shade and I'll be sad if that's all lost like it was in this picture."
