Before this thread, I'd heard of Mad Max, but I thought there was only one movie...and I didn't think "Road Warrior" was part of the title of that one movie.
After this thread, I now know that there is apparently more than 1 movie...but I still don't care very much. I never saw that one I knew about...and after recent events, I am even less likely than before to ever see it.
Truthfully, if you have a girlfriend who likes even SOME scifi, you ought to be happy. There are not all that many of us, to be honest.
