It's just a lot rougher than you seem to want to believe -- not so much "intent" as "Yeah, this might work." Fans make such a big deal over "creators' intent," whereas we creators are just floundering along, making up crap as we go and hoping it doesn't turn out to be a complete mess. Usually our only intent is to get to the deadline with something resembling a coherent work. And even then, what we turn in is often just what we had to settle for when time ran out. That's not what I'm talking about at all. It's not about this one idea, it's about clarifying how creativity works. Sure, but not to the point that it limits them. Every creation evolves and changes. Every writers' guide contains suggestions that get ignored as well as ones that get used. Like I said, they're the paints on the palette. Potential, not intent. They're there to be used if they're needed, but they're optional.
