Someone very clever--or with too much time on their hands--came up with the "Science Fiction Periodic Table." This chart catalogues sci-fi movies and TV programs considered to be"pure elements." While some of the shows not listed on the chart are considered to be compound derivaties of the elemental stories.

However, there is a debate on The Miniatures Page (TMP), where I found this, on why certain movies & programs didn't "make the chart":
I'm a retired USAF TACP (Tactical Air Control Party) member, now working for Washington State Emergency Management. In addition to being an Emergency Operations Specialist at my day/night/weekend job, I'm a Foreign Affairs Specialist, gamer and writer.
I maintain three blogs as an on-line platform. "Stern Rake Studio," my central site, explores a variety of topics on gaming, pop-culture and writing. "Station WTFO" is where I post comments and discussions on the national and international issues that concern us. Finally, "The Redshift Chronicles," is a spin-off of "Stern Rake Studio." This site focuses on sci-fi gaming and is home to my long-form webcomic "Breakout from Bongolaan."
