We watch it as a family. I've only watched the past 4 or 5 years. DH got me into it when we started dating.
I think it's great to see how the different personalities interact. As a family we discuss who we could hang with and who drives us nuts and why. What strategies work, and why. It's nice. And we love it when the good guys win!
And loved seeing the teacher win last season, and how 'crafty' he was, in more ways than one! He wasn't the Survivor 'pretty' stereotype at all!! Very cool.
Rupert will always be our favorite Survivor character, though.
