Quoted from coasterguy:
Regarding the theme. I have spoke with many folks outside the pinball world about WOZ. It is pretty amazing how many of them could care less about pinball until I say WOZ is coming and it has never been done before. They typically light up bit and say I want to come see it when you get it. Ladies and kids typically and some men but interested in the least. Good for pinball. I do believe that Jack picked a good starter theme. I really do.
Just about anybody that is over the age of 38 remembers when there were only 3 major channels on TV (not counting PBS the 3 were ABC, NBC, and CBS). Also, the Wizard of Oz movie was only broadcasted once a year and was not available on VHS, etc. like it is now, thus for many it was an annual family event to watch the movie. I have nothing but great memories from each year, popping some popcorn and watching the movie with my brother and parents.
