I don't watch much TV either, but when I do, it's for escapism.  So I have favored shows like ST:TOS, ST:TNG, Firefly, LOST (well, at least the first season), Jericho, and even the current Once Upon A Time.  Nothing real or believable in these shows, just an escape from the day-to-day routine.  Even Gilligan's Island qualified when I was a kid!  The only "reality show" that I've watched is The Amazing Race.  Not so much for it's content (which is actually pretty bad), but for the filming in different locations - I can pick out and dream about places I might want to visit some day from their photography.  I do like Dual Survival though.  I like to see how they think through and solve puzzles.  Even if it's an artificial puzzle or a stupid one.  Sometimes their solution provides me with insight I didn't have before, and other times it provides me a platform to say "I wouldn't have done it that way".  Either outcome can be a learning/reinforcement experience.
