There is a big difference between watxhing a movie and operating a device where your input makes things move on the screen, you notice the depay way more.
I find that watching something like a fast-pan in 24fps footage on a modern LCD is horrific. CRTs used to inherently smooth this sort of thing out, but now we get these harsh frame transitions. As much as the soap-opera-effect is maligned, a high refresh rate LCD needs some form of motion prediction for low frame rate content.
