Why is it unthinkable that not everything new is also better? 3D is pretty much the same thing. In animation you have the same issue with the uncanny valley - people accept a certain realism, but once you cross a realism threshold, you suddenly need to deliver perfection, or people notice something is off. HFR, for me, plays into the uncanny valley. I think the future is in adaptive framerates. HFR shines in the big sweeping shots and when quick movements or panning is required. but it absolutely sucks for close ups and dialogue heavy scenes. another example for this are music videos - notice how they could have been HFR for a long time already, but aren't? they are being filmed sped up on purpose and then slowed down for the final product. just to make them appear larger than life.
