For those that grew up watching the movies from the 60s, 70s and 80s, going back to watch them can be a mixed bag if you have also watched a lot of current movies.
The old movies were slower moving and had fewer tricks and special effects. The actors and movie studios didn't rely on fancy digital effects.
One thing that I really notice is how the movies appear more like a stage play where the viewer stays in one place and watches the actors/players move around. Later movies have more camera angles and much more editing.
In the 80s, a book was released titled "Death by a thousand cuts" that discussed how Hollywood productions have cheapened the viewing experience by way of TV shows and movies using multiple cameras and faster editing of scenes.
For example, watch any of the fight scenes from movies in the 70s...Even Enter The Dragon. It was almost as if you were there. Think of the fight scenes...one continuous scene from start to finish. Conversely, todays fight scenes are done with either CGI or cameras but have different angled shots that often change every 1 to 1.5 seconds. The rapid editing and assembly of these scenes can be distracting and not as pleasing to watch.
