Taika Waititi and Kevin Smith have spoken up in response to Martin Scorsese saying that Marvel films are “not cinema,” and both are in agreement that they are, in fact, cinema.
Scorsese’s comments came from an interview with Empire Magazine where he was asked about the superhero genre and the MCU. He said “I don’t see them. I tried, you know? But that’s not cinema. 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.”
