Couldn't agree more. Endgame's run was and is a phenomenal achievement. I think one just has to look at the top five movies when each of these were released in order to get a picture on what was possible at the time. When Titanic released the second highest grossing movie hadn't even reached $1 billion. When Avatar released the second highest grossing movie hadn't even reached $2 billion and the third hadn't reached $1.5. The difference in the top 5 movies now is a much smaller number.
