I liked many of the movies mentioned so far, but I wouldn’t think many have the lasting appeal of The Godfather, Casablanca or Josey Wales. The last five years may not have any that meet that standard.
I agree that La La Land might, because of what it is and because it is very good. But it would be in the musical, dance rom-com genere, not as one of the greatest movies of all time, all categories.
I agree with Mad Max: Fury Road because it’s good in and of itself and part of a cult series. But again, not an all-time, all-categories inclusion.
I think The Post might have some staying power in tandem with All the President’s Men, particularly because of its unique perspective, being about a woman business owner’s existential crisis. Very good movie, but not a seminal one.
I think BlacKkKlansman is a great movie, but very tough to watch or enjoy. It should survive as perhaps the greatest movie made by one of our era’s most insightful film makers, or as one of the greatest true story cop movies. But because of its focus on racism and institutionalized racism, it won’t reach a very big general audience. So it can’t make the all-time, all categories cut for most.
