There were a lot of fads and cultural highlights of the 80's that I missed.
I was never devoted to a member of New Kids on the Block. I watched maybe three episodes of Saved By The Bell. I didn't see Labyrinth or The Sandlot until college. I'm pretty sure I never wore a side ponytail on purpose, or a sweatshirt hanging off one shoulder with a bright leotard underneath.
But, thanks to my geek of a father, I definitely saw TRON. Many times. And I'll probably watch the new one with him too. (Even now, in a game of SceneIt I am fully dependable in the area of 80's science fiction.)
