All good advice. I'm regimented in that I always have my final read through off paper (less pages to print with screenplays) and it's often at that stage where certain things leap off the page that *somehow* went unnoticed on the screen. Also, having the patience to let things settle, as you say, is hugely important.

I read a wonderful story about Picasso regarding distance. He apparently wouldn't claim any work as being finished until he had looked at it in a mirror from across his studio. It was this action that allowed him to become less attached and created a sense of distance and perspective that empowered him to critique his own work.
