Great observations, thanks. One thing I thought of as I read it was that, just as film executives get enamored with things that feel new--like deals--and eschew things that feel old--like development--so too do writers often feel the pull of the new script idea, which seems so much more clear and vibrant than the current one they're in the middle of writing. This is especially true if you're adrift in the sea of Act 2, trying to keep things moving and fresh, trying to concoct twists or give characters more depth.
But executives have to remember that development is where the movie actually gets made, and we writers (and I'm pointing a finger at myself here) need to remember that slogging through the script, turning out the pages and the rewrites, is how that initial alluring idea of ours gets turned into an actual finished screenplay.
