I would do the same with my children. And I will also teach them about how to use their mind effectively (memory tricks, problem solving, etc), and they will be able to see for themselves how watching movies affects their mind. Plus, I hope I'll be able to offer them enough real-life enjoyment so that they will not need any movies.
Update on my trial:
I have never once felt tired during those 8 days without movies.
Before, especially while watching movies, I would sometimes feel an overwhelming tiredness, even though I was lying in bed watching. I didn't know what was wrong with me. I never felt tired doing Tai Chi or even while walking around the city for 7 hours in a row. But while sitting down watching a movie, I couldn't find my place on the chair, it seemed exhausting. Now, while reading/going out, working out, whatever I'm doing, I never feel that tiredness. Even if I feel physically tired, I don't feel like fainting as before, I just feel like sitting down/taking a shower or something.
When I was watching movies, whenever I would get up and make myself a tea and wash some dishes, etc, I felt instantly recharged with energy. I used to think that washing dishes is the most energy-boosting activity of all. I thought the zone with the kitchen sink had extremely positive energy in my apartment, and I thought that was why I felt so energized when I went there. But now I know that it was just the fact that, when going to wash dishes, I would take a break from watching a movie, and in contrast with the movie's mind-numbing effect, dish-washing seemed very energizing. Plus - dish washing is like a meditation - you pay attention to what you do, and your mind and body are one
