Which movies have aged like fine wine? (either in their message or cinematography)

I recently saw 'Don't Look Now' (1973). Good picture, a little slow perhaps by today's standards but worthy of any movie enjoyer's time! So this movie was shot in Venice. Venice itself being an already beautiful spot to film even today. The way we get to look in a time capsule of Venice in the 70s makes the movie that much better!

People in the 70s could not in fact appreciate it the same way we do now. Concurrently we also can't do it for today's movies. Some movies can only be truly appreciated over time is what I believe. This matter can be expressed in both the movie's message or, as I did, its cinematography. Hence my question now to you.
