See, I've never felt that way.
I had a decent Sony camcorder that had different shooting mode speeds, including sports. The sports mode increased the shutter speed, without adjusting the frames per second, and the end result looks exactly like what frame interpolation does.
Motion REQUIRES blur. Wave your hand in front of your face - it's not a stop motion hand moving back and forth, but a blurred hand.
Frame interpolation, at medium levels can look very good, if it doesn't overly deblur what we are seeing, but if you remove blur completely, then you end up with what video games looked like ten years ago. Video game manufacturers spent a ton of time and money ADDING blur because of how much more lifelike it made the image.
Now, LCD manufacturers are removing the blur, and what we end up with is extremely unnatural 'video game' looking images. I've never seen a soap opera which has looked as bad as heavy frame interpolation does on the LCD displays.
