Telling us to obey instinct is like telling us to obey 'people.' People say different things: so do instincts. Our instincts are at war... Each instinct, if you listen to it, will claim to be gratified at the expense of the rest. ↗
As far as expense, I think if 'Twilight' does well enough, then we should be able to do the big expensive stuff for the sequels. I mean, we have to have werewolves, there's no way around it. They have to be there. ↗
