io9 had a good explanation of Why Frame Rate Matters. The only high frame rate movie I've seen is the first Hobbit movie. I saw it in 48 FPS in 3D and thought it looked terrible. Some friends said they got used to it after 15-30 minutes but I never did (and it was a long movie). It also didn't help that I didn't like the movie (I saw the second on cable and liked it even less and haven't seen the third).
