"I want each season to feel new and special. I don't want it to feel, "Oh, more of this." That's something that's easy to do in the first three seasons, and harder to do as you go. I'd rather err on the side of blowing up everything and being like, "Why did you do that? There was more story to tell there," and moving the family to Mexico like on Weeds, instead of people going, "Oh, we've seen this already. We're tired of this.""
