Possibly the largest hurdle many lovers of genre movies, books and television shows have to jump with non-believers is the big scifi ultimatum. Sure they love me, but can they love my Star Wars ? It's all fun and games until the Firefly box is opened, and all of a sudden you're caught defending space pirates. How I Met Your Mother's season premiere perfectly covered this silly question that those of us with short fuses and huge science fiction collections often find ourselves in. Season spoilers for HIMYM . It's a sweet look at the geeking out we all do when our most favorite movie is on and you really, really hope that your friend/buddy/significant other/or homeless guy on the street will enjoy it as much as you will. The nice thing about HIMYM's take on the "deal breaker" movie is that at least Sarah Chalke was smart enough to lie. Which is my advice to those of you just getting into the scifi game. Just this week a beautiful girl approached me and asked what she should do as she "discovered" her fiances' in-depth collection of Star Trek episodes. I told her to ask him to play her his favorite episodes that he thought she would like, open a bottle of wine (or two), and if she didn't like it just let him know he can have all the fun friend time he wants with his buddies that want to come over for Trek marathons. I can not count the number of times where I had to convince past boys to watch "the movie with the big bug creatures" again (their quote) but when you find the right person to relish in your scifi joy (friend or familiar) the 77th time around is even sweeter. My favorite can-not-live-with-out-deal-breaker-if-they-don't-at-least-pretend-to-like-it movie is and probably always will be Aliens . What's yours?
