Watch a soap opera from Latin America. The actors' faces are lit from every direction to remove shadows. And they are backlit to make them "pop". In other words, to make them stand out from the background. To my eye, interpolation does the exact same thing. It's like they used too many lights and it makes the layers of depth in the shot "separate" from each other and look flat. It makes the whole shot look completely fake to my eye.
