Panni, unfortunately, it's always the people who have studied and lived with the script the least who have the most power over it.
Everyone is always very tentative in telling the director how to direct, or the art designer how to design, or the composer how to score,or even the lighting technician how to hang a light, and, God knows, if you told some Iatse guy where to move a prop, you'd probably have a hammer dropped on your head from the catwalk. But everybody and his brother has no compunction or hesitation whatever in telling the writer how to write.
