I thought of dozens of ways to improve on the current big movie theatre model but ultimately decided it was much simpler and easier to just have a good home theatre system for private use. Also I figured it was so obvious how to improve and innovate in that area that if it hadn't already been done by now there were probably nasty little complexities or political/bureaucratic swamps involved. Because there were no significant purely physical or technical challenges.
