I have heard it claimed that because historically high-budget hollywood films were shot on film at 24fps, while low-budget TV content was shot on tape at 30fps interlaced to 60fps, people came to think the lower framerate is "cinematic" and that higher framerates "don't look right"

Personally I'm not enough of a film buff to notice the difference. Apparently film enthusiasts do notice, and care a great deal, though.
