I recorded Snakes on a Plane the other night for WinnieTheWoot and I to watch since we've never seen it before but frequently reference the "motherfucking snakes on this motherfucking plane" line, much to the dismay of her mother. We're in the middle of season five of Stargate:SG1. We watched Buffy last year and BSG the year before that.
What else do you figure we should watch (TV or film) to put more notches in our geek belts? Don't worry about hitting things we have seen, there's too many for me to list them. I will say that we've seen nearly every superhero from the last ten years.
