Yea, I don't get the appeal of watching someone pretend they haven't seen "The Empire Strikes Back" and are watching it for the first time and are agog at the the twist.
I don't know... I'm as familiar with it as anyone of my generation, but I honestly can't remember when I actually saw it last referenced in media or popular culture. I'd definitely be skeptical of anyone close to my age being unaware of it, though.
