But here is the thing. Scorsese saw a few, and even says they are well made and all that. he was using the phrase “cinema” in a very esoteric, scholarly and insular sense.Being all like "Marvel movies are all the same lel" is indefensible nonsense. And not even seeing the movies before misrepresenting them is next level shitposting.
This behavior would be embarrassing enough from some nobody DC fanboy, but from a respected creator in the industry? Outrageously tactless.
Keep in mind that Scorsese and Coppola are actual film historians and scholars, and not only awarded Directors. So saying their opinion is not worth because they are just "old men", would not makes their views and opinions the embarrassing ones.
