People should try reading more books and watch less TV/streaming precisely for this reason. Also maybe if you want to watch a movie consider watching older movies.

This is a fascinating article/podcast that talks about this but is focused on how it impacts your attention span and has data: https://www.apa.org/news/podcasts/speaking-of-psychology/attention-spans

Mark: So I was very surprised to learn that TV and film shot lengths have decreased over the years. They started out much longer. They now average about four seconds a shot length. That’s on average. If you watch MTV music videos, they’re much shorter. They’re only a couple of seconds. So we’ve become accustomed to seeing very fast shot lengths when we look at TV and film. Even commercials have shortened in length. Commercials used to be much longer. Now it’s not uncommon to see six-second commercials, even shorter than that. Now it’s a chicken and egg question. We don’t know if TV and film have affected our attention spans on computers and phones. We don’t know if our attention spans have affected the decision-making of film editors and directors. We don’t know exactly if there is any causal connection we see these two parallel trends.

It could be the case that directors and editors are influenced by their own short attention spans when they create these film shots or it could be that they’re creating short film shots because they think that’s what the viewer wants to see. But this has become quite ubiquitous. In fact, on YouTube, there’s a particular YouTube aesthetic which uses jump cuts. So when you’re watching a YouTube film, the film becomes very jumpy. The natural pauses that people make when they speak it is removed. So the idea is to pack more content into a shorter amount of time. So we’re seeing short lengths of content from all directions. It’s not just what we’re attending to on computers and phones.
