When we met, Bee had never seen the original Star Wars trilogy. Or Die Hard.
When she told me that, I had to seriously rethink our relationship. If I had known that she had never seen either of the first two Godfathers, I don't know that we would've gotten married! It's on me though that I've never sat down to watch the Godfathers with her.
In her defense though, I've never seen Ghost.
What movies has your SO not seen that you feel you must rectify? What about you... are there holes in your cinematic education?
