The part about good art not being about communication is just plain wrong. Good artists (and yes you can argue that art is subjective) spend thousands of hours studying the fundamentals—perspective,light,colour,value,proportion,anatomy, not to mention the dexterity to making a line—so that they can communicate to the viewer in the best way that suits the piece of art.
Sustaining the attention on an art piece unlocks things that you missed the first time due to having an untrained eye, much like reading a good book.
