Yeah I'm seeing Catching Fire for sure. Can't wait.

How to Train Your Dragon was fine on its own. There's nothing else that was established in the first film that needs doing, and now that the main character is already an established hero and has changed his entire community's idea of what it means to be strong, there's no easy way they can go through the typical hero arc without making him seem irrational (which we know he's not, he's mild-mannered and intelligent) or selfish (which, again, he's not). Or they could throw in some stupid plot device that makes him have to be neither of those things, which will test my suspension of disbelief.
