I believe 24Hz works in movies because the way cinemas are set up. The image projected onto canvas in a dark/dim room "burn" in (not sure what the correct term is) which can make it appear smoother. This is why they can get away with it in cinemas. Plus it's also a consistent 24Hz, which in games (and Way of Water) isn't.

People used this excuse for games, to make games more "cinematic", but that was just an absolute horseshit excuse for games being poorly optimised. Especially if the framerate wasn't locked to 24FPS, and because home monitors and TVs don't work the same as cinema projectors.

I'm sure if all cinemas and media would move to a higher framerate/Hz it would eventually just feel normal though. It just often takes a lot of time getting used to, especially for cinema experiences.
