Still understanding I can never really achieve to see what the director wanted me to see precisely, what is more important? That I see something close thereto, or something that most pleases my eye?
Here's what I say to that: I have never had anybody spend serious time with an accurate, and high-quality image not be blown away by how "good" "pleasing" "amazing" or whatever nonsensical subjective word you'd like to insert, the image is. In my view, those words are only meaningful in describing the accuracy of the reproduction, but my point is that for people who just want something most pleasing to the eye, if you actually spend time with a variety of images and actually care about how "good" they look, you will invariably end up with an accurately calibrated reproduction chain. Because when you do view content that should appear natural, it will appear natural, and that will look simply amazing. With whatever willy-nilly preferred nonsense you might arrive at, it will never appear natural.
That being said, if you don't believe or care about quality images, don't get your display calibrated. Just don't pretend that you care about image fidelity. It's a free country, do what you want. Nobody is forcing you to get the best TV you can, or get the best picture and sound you can. If you like horrible images, or like horrible sound, great!
