The only reason for this is because movies have always been 24fps and soap opera's have always been 60fps. It's just how your brain has been conditioned.
60fps is objectively better.
Except that is clearly not, because most people say that even 48fps look stupid in movies. Although I don't think it's quite the same thing in movies and in games, it's kind of confusing. In games it's about fluidity versus stutter, whereas in film it's about the visual look.
