When I walk out my balcony I see an expansive view and I can see and make out lots and lots of detail whenever I focus on one part of the scene. It was not until I photographed the view with my 60MP back that I could see an image file that allowed me to see what I saw in real life. I can make a very large print from that file and look at it as I would the view in actuality, sometimes appreciating it as a whole but other times focusing on the little details in the scene without the photographic shortcomings usually present in lesser files getting in the way of the experience. It is like looking through perfectly clear glass at a real scene.
I found that it takes from 60-120MP for one to be able to achieve that effect. I love it, but it is not for everything.
In movies besides resolution you have motion rendering. The type of shutter (and setting) and recorded framerate + ultimately the display framerate has a lot to do with it. Most people prefer fluid motion. A high frequency of display framerate combined with high resolution display shows more detail yes but the motion might look too smooth or video like. I prefer some motion blur in the moving parts of the image, makes everything a tad softer but more pleasing. It is an extensive topic that can be discussed for years.
