Well, I like Return of the King, so maybe "suspend disbelief" is the wrong phrase--I think it makes the spectacle harder to appreciate. I promise you that I went into the theater ready to overlook the inherent corniness of Middle Earth. You do see Rivendell in greater clarity, but you also see all the costumes and props and makeup and choreography in greater clarity and it destroys some of the illusion. Main point is, for me, it wasn't that HFR was "too real" or "too clear," it's that what was on screen hadn't caught up with the framerate. (3D's a whole different issue.) Anyway, I'll be interested in hearing what you think of the format once you've seen it.
