The Oscar-winning director Martin Scorsese ruffled some feathers when he told The Guardian that he’s not a fan of Marvel movies.

“I tried, you know?” Scorsese said of attempting to watch a superhero film released by the studio. “But that’s not cinema.”

The Irishman director continued, “Honestly, the closest I can think of them, as well made as they are, with actors doing the best they can under the circumstances, is theme parks.”

“It isn’t the cinema of human beings trying to convey emotional, psychological experiences to another human being,” the 76-year-old Scorsese said.

Several people on Twitter, and major league filmmakers Joss Whedon, who directed 2012’s The Avengers and 2015’s Avengers: Age of Ultron, and James Gunn, the director and writer behind the Guardians of the Galaxy franchise expressed outrage.

The 55-year-old Whedon tweeted: “‘It isn’t the cinema of human beings trying to convey emotional, psychological experiences to another human being.’ I first think of @JamesGunn. How his heart & guts are packed into GOTG. I revere Marty, & I do see his point, but… Well there’s a reason why ‘I’m always angry’.”

Gunn, 53, tweeted he was “saddened” by Scorsese’s response to superhero films, writing, “Martin Scorsese is one of my 5 favorite living filmmakers. I was outraged when people picketed The Last Temptation of Christ without having seen the film. I’m saddened that he’s now judging my films in the same way.”

Marvel Studios president Kevin Feige said: “Maybe it’s easy to dismiss VFX or flying people or spaceships or billion-dollar grosses. I think it is easy to say that you have already been awarded in a certain way. “Alfred Hitchcock never won the Best Director Oscar, so it’s very nice getting an award, but it doesn’t mean everything. I would much rather be in a room full of engaged fans.”

Scorsese’s latest film The Irishman, starring Robert De Niro, hits theaters November 1st and will be available for streaming November 27th.
