Good man!
I had my 1 year old daughter dancing to the Battlestar Galactica theme every morning when I'd put on a few episodes to start the day. The Alien education will commence when I'm reasonably sure it won't scare the holy hell out of her. I saw Aliens when I was 10, and it scared me, but I figure at that point it's just a part of growing up. Looking back, that fear is one of my favorite things about the films. Predator, also. Who hasn't had dreams of being chased around your house or neighborhood by a Predator, probably while they stab all of your friends and family?
There is hope for the future!
