Francis Coppola, quoted during an appearance at the Lyon Film Festival: “When Martin Scorsese says that the Marvel pictures are not cinema, he’s right because we expect to learn something from cinema, we expect to gain something, some enlightenment, some knowledge, some inspiration. Martin was kind when he said it’s not cinema. He didn’t say it’s despicable, which I just say it is.”
I say that Avengers: Endgame is cinema; ditto the first two Captain America flicks and the first Ant Man. At least these.
