And to add to the above, traditionally, all movies were made in 24fps frame speed. Most still are, but there is a trend to double that to 48fps. A lot of older people do not like newer movies in 48fps because the frames are more clear and to them it looks like a soap opera clear effect. Especially in movies where a lot of action takes place. In 24fps, the action is someone blurred so the eye only focuses on the bigger picture.
On the other hand, nature documentaries like the Planet Earth series are shot in 48fps because the camera movement is relatively slow for maximum high resolution detail viewing and I must say that Planet Earth II is visually stunning in 4K and almost like looking through a window. Anyway, movie watching is...
