I think most people know the concept of difficult family situations. So I try to just ground a very big concept in something we can all relate to on some level.
Mark MillarThe big thing is it's a domestic drama. Everything else in science fiction tends to be high-concept. Really for the last 40 years or so I think sci-fi's been a little cold and a little inhuman quite often - certainly since the 1980s - and I really wanted to do something that almost felt like a regular, real-life drama but just set it in a sci-fi setting. I think the best stuff is always like that.
