Only on hn would you have someone miss the point of art this hard. That's not art anymore, that's not creative.
And art is a term that's quite ambiguous and often means different things to different people. I think you would agree that a lot of people consume movies simply as entertainment. From that perspective, it matters less where the data about pixels came from. This is coming from a person who loves movies, artsy, not artsy, and everything in between.
