The last point from the quote is important, i.e., from Scorsese, Coppola, and Scott. It's not just in superhero movies but many Hollywood movies: cardboard cutout characters, lack of character development leading to unsympathetic protagonists, a heavy reliance on spectacle instead of a buildup leading to that, and recently a strong emphasis on forcing woke agendas.
Some of these problems have shown up in some of the recent movies in the Alien and Predator franchises, and it's possible that even if directors and writers try to avoid these issues they show up because producers force changes to stories.
