Star Wars hands down.
I loved watching Star Trek, but it is/was the most liberal utopian groupthink backstory. Star Wars has a much more conservative ideology.
My kids started watching "Clone Wars" on Cartoon network--cheesy computer animation serials that fill in the pieces of the timeline in the [sucky] prequels. I was EXTREMELY shocked at how pro-right the storylines are--even to the point of teaching MORALS. Which means they "will cancel the he!! out of it," to misquote MB.
