When Kevin Feige made his choice for the most important superhero movie of all time, he wasn’t just looking at the fan’s reactions or critics' reviews. He was also looking at how a film can shape the entire world of cinema, which is something you’ll want to keep in mind when you read his pick.

The Marvel boss believes DC's "Batman & Robin" was perhaps the most important and influential comic book movie ever made. "It was so bad that it demanded a new way of doing things," he reasoned in an interview with the Los Angeles Times.

He went on to explain that early MCU movies like "Iron Man," and "Thor," would have never even been possible had "Batman & Robin" not bombed so badly with critics and fans. "It created the opportunity to do 'X-Men' and 'Spider-Man,' adaptations that respected the source material and adaptations that were not campy," Feige said.
