There are so many. When I was single, living alone, with no cable and little money, I watched the same DVDs over and over on my 32" tube TV. Then I got married, bought a 50" plasma, had kids, signed up for cable, and my movie viewing dropped off significantly. I still have so many of those DVDs I lived off of when I was single. I am about to buy a new TV and it occurred to me so many of my favorite movies I never watched on my plasma.
Gun to my head Star Trek II is my favorite film. I am making a point of it being one of my first viewings on the new TV once it's hooked up.
