It’s the latest thing. I profoundly dislike it. Maybe the fad will pass and directors will just be able to show action again, someday. It worked for John Ford, after all.
One movie it worked in was “Outlander”, and it worked because it was used in the crash scene only.
And it wasn’t as bad or “ADHD” in that movie as in other shows.
Recent shows act as if the camera is attached to a six year old who has been dosed with sugar and amphetamines before turning him loose.
