Low frame rate is the reason I can't take film seriously as an art form. It seems to me utterly bizarre that people would choose a frame rate that can't show realistic action scenes. Fight scenes have annoying foley sound effects partly to compensate for the frame rate making fast movement invisible. And camera work is severely limited - fast pans are near unwatchable. I've seen 60fps Showscan film and it's such a huge improvement I can't understand how people could still argue for 24fps. It can only be "baby duck effect", where people like something only because they grew up with it. Imagine if music wasn't considered musical unless you listened to it from a wax cylinder. Technology has moved on and we can do much better.
I realize that cost was an issue, but with digital production that's no longer the case. And yes, it's true that higher frame rate exposes flaws in sets and props, but that's no excuse to stick with low frame rate. The correct solution is to improve those sets/props. 60fps should be considered the bare minimum.
