Or that the move from HD to 4K is near-worthless without a framerate increase?

Maybe it's not bad enough to match your personal definition of 'choppy', but 24fps is an unfortunate compromise made in the days when you had to feed costly physical film into movie cameras.

And now everyone is so familiar with 'the cinematic look', we're stuck with 'movies should look like that, as that's how they've always looked', anything different is assumed to be worse, and we're never going to learn how to do high-framerate filmmaking well as the early attempts were so quickly rejected.
