I hate that mode that generates extra frames to make something look like 60fps. That literally gives me motion sickness and migraines.
I have nothing against The Hobbit being in 48fps. It's like Doug Trumbull's Showscan format. And I believe that the original Star Tours ride film was shot at 30fps instead of 24, and it doesn't look like a soap opera.
It's not the same as this awful 120Hz/fake 60fps thing that makes 24fps film move like a student film shot on a camcorder.
