Most of my JW life I used to consider movies a waste of time. I would occasionally watch one with friends, but as long as I didn't choose them I was not that interested. Once, a few months after I had been df'd, I went to a movie theater with a friend of mine; the movie she wanted to see wasn't played, there was a Bergman movie instead, The Communicants. I was stunned. During the next couple of years I went to the movies every other day, starting with Bergman's almost complete filmography, and gradually discovering the wealth of classic cinematography. A great thing in Paris is that the best movies from all times and all countries are almost constantly available (and back then it was cheap). Now video completes this very helpfully, as some movies are worth being seen many times.
What I saw over the years helped me and changed me as much as the books I've read. To me that was certainly not a waste of time.
