Cognitive psychologist Donald Norman has written a book called "Things that Make Us Smart" which contains some reflections over how people perceive and use things. The book is great, highly recommended but the "book vs movie" discussion jogged my memory of one particular part where I recall Donald Norman reasoning about experiential and reflective entertainment. Books are reflective, TV is most often experiential and good movies are both. His conclusion, if I recall correctly, was that people today are too obsessed with experiental rather than reflective media. There's room for both but they should be balanced and this imbalance we see today is making people less prone to question or try to understand the world.
