A couple of years ago, I rewatched some episodes of a 70s BBC drama called "Survivors" (the plot etc. is irrelevant in the current context). In the very first episode there's a scene where a woman who is looking for her son but has no idea where he might be walks across a very small wooden bridge over an even small creek. She stops in the middle, holds the rail on the bridge and looks down at the water. The camera shows us what she sees. For somewhere between 30 and 60 seconds, we just see the water in the creek flowing. It's not even particularly beautiful.

Aesthetics sure can change a lot, even within a single lifetime.
