I keep waiting for a paradigm shift to happen that will let network and studio execs see that sci-fi is the same as any other genre in terms of how you approach it - logically, character-based, with challenging ideas and forward thinking - but I worry that it might never happen in my lifetime.

Every time I got 'Amazing Spider-Man' or 'Fantastic Four' or another book firmly on the rails, we got pulled into some big event book or crossover and it cost momentum and messed badly with the pacing and structure of the book.

In every other science fiction series, humans are at the top of the food chain. In the 'Babylon 5' universe, they're in the bottom third.

Follow your passion. The rest will attend to itself. If I can do it, anybody can do it. It's possible. And it's your turn. So go for it. It's never too late to become what you always wanted to be in the first place.

It's really important to me to keep growing as a writer, to look for new challenges and be harshly critical of my own work in order to learn and tell better stories.

I was very clear that I wanted to keep 'Thor' out of the rest of the Marvel universe for no less than the first six issues. And the success of the book, I think, speaks well to that decision.

I have friends in different parts of the world, and they'll all go online at the same time and all pull up a movie and hit play, at the same moment, and then they'll comment to each other about it. They're sharing an experience, even though they're on different parts of the planet.
