"Beautiful" is a term that can be limiting, in the sense of appreciating the technical and inspirational arts that go into a movie, and may extend the life of the movie and the appreciation of the movie. I had a neighbor who was a seamstress who insisted on seeing the movie "Restoration" with me and boy was she right. The film had a good plot but has not lived in critical memory, but the fabrics in the film were so magnificent you got a sense of texture from them.

Also we are in an age of wonderful and important documentaries. I will watch anything that David Attenboroough narrates. He seems to be spending a large amount of his time recording for the BBC and like film sources.

There was an incredibly skillful documentary on the intimate lives of various bees that a great nature photographer put together in his backyard during Covid isolation. Magnificent.

As for whether or not films maintain their 'relevance' or their appropriateness over the years, that's asking a lot, but it is an interesting topic. There are flicks I enjoyed very much when I was young which I am more or less sanguine about confessing these days. One I admire as both beautiful, well cast, well acted, and relevant its entire run is "In the Heat of the Night." 55 years old, now. Just rewatched and enjoyed every minute.
