I wouldn't call it "fetishizing" though; not all of them anyway. Motion blur happens with real vision, so anything without blur would look odd. There's cinematic exaggeration, of course. 24 FPS is indeed entirely artificial, but I wouldn't call it a fetish: if you've grown with 24 FPS movies, a higher frame rate will paradoxically look artificial! It's not a snobby thing, maybe it's an "uncanny valley" thing? To me h…
>Motion blur happens with real vision, so anything without blur would look odd. You watch the video with your eyes so it's not possible to get "odd"-looking lack of blur. There's no need to add extra motion blur on top of the naturally occurring blur.
In practice, I think the kind of blur that happens when you're looking at a physical object vs an object projected on a crisp, lit screen, with postprocessing/color grading/light meant for the screen, is different. I'm also not sure whatever is captured by a camera looks the same in motion than what you see with your eyes; in effect even the best camera is always introducing a distortion, so it has to be corrected somehow. The camera is "faking" movement, it's just that it's more convincing than a simple cartoon as a sequence of static drawings. (Note I'm speaking from intuition, I'm not making a formal claim!).
That's why (IMO) you don't need "motion blur" effects for live theater, but you do for cinema and TV shows: real physical objects and people vs whatever exists on a flat surface that emits light.
