You make an important point re the visual vs. the written. These days it's all about the visual. How does that compare to writing? What does that do to us?
I'll dare to say it is like eating junk food vs. nourishing food for the brain. Went and got a DVD of Great Expectations. Nice to watch, to be sure, but no food for thought, for the imagination, for delight in words, for creativity in the mind, for any emotional reaction. Interesting to think about the comparison. Suppose it depends on the person.
