The noise you hear after people see something you do--whether it's a TV show or a movie--that always makes you see that thing slightly differently. Without question. The ability of a television series to make adjustments is something you've got to take advantage of. And test-screening a movie can be helpful too. But the part that can be dangerous is when you take those notes as gospel, instead of taking them with a grain of salt. The key is to use the response as one of the tools in your box, as opposed to using it to determine what you do.
