Motion can/should be improved too. I recently attended a musical/play. At one point, human silhouettes were moving on what looked like a screen. I was trying to figure out if it was a projected image or if actors were acting behind a mesh, semi transparent screen. I was convinced that it was a projected image, but then noticed that the motion seemed too smooth. Something seemed more natural about the way they were moving. The movement/motion was my only visual clue that it wasn't a projected image and that they were in fact actors behind a screen. There must be some sort of subtle way that I can't explain scientifically about the way motion is handled with our tvs that could be improved upon to make the image appear more realistic and natural.
