It was a movie that blew the minds of fanboys everywhere, made a tonne of money for Disney and Marvel and set the ball rolling for their next run of comic book movies. Many might even say that it was the film that made Warner Bros. sit up and greenlight Batman vs. Superman. But there is one person who has some criticisms about The Avengers – its director Joss Whedon.

In an interview with Entertainment Weekly, the geek guru said, “When I think of a great film, I think of something that’s either structured so perfectly like The Matrix or made so lovingly like The Godfather Part II,” he said. “There was haphazardness in the way [The Avengers] comes together — not just the people, but the scenes. I don’t think you’d look at it and go, ‘This is a model of perfect structure.’ You’d go, ‘This is working.'”

But with that said, Whedon plans to use this to make 2015’s sequel The Avengers: Age of Ultron better, “I want to be clearer about how I engage the audience, and where I take them,” he said. “I want more control visually, more time to prep it. Not that I didn’t dictate every shot — I did. But there’s only so much you can do when you’re making a summer film when the ball is already rolling as fast as it was when I got in. Why do it again if you can’t do it better?”

Whedon was quick to point out though that he is a fan of his record breaking movie, “I like [The Avengers]. I’m proud of it and I like its imperfections. The thing I cared most about — making a summer movie like the ones from my childhood — is the thing that I pulled off.”

The Avengers: Age of Ultron is set for release May 1st 2015, with James Spader as the evil Ultron taking on the returning Robert Downey Jr, Chris Evans, Chris Hemsworth, Mark Ruffalo, Scarlett Johansson and Jeremy Renner.
