It's not a video game, you're not in control, so the standards are different.

In a high CGI film, like Avatar 2 for instance, where the entire film is mainly CGI, then shooting in 48fps has an advantage and looks much better. You simply have more clear information on the screen per second that way, which helps for 3D and for CGI detail.

The only issue really is that camera movement needs some experimentation to get right. Some movements in 48fps are too quick or too smooth and this makes them jarring to general audiences who are used to 24fps. Actors also move a certain way for 24fps (they slow down certain motions for instance), so they'll need to fiddle with that as well in 48fps.
