Story Limit

You know those films, novels, and plays that seem to go on and on and on with no end in sight? That's because they don't have in place a strong and consistent Story Limit. Set up whether the story is limited by Options or Time in the very first Act, remind us in the subsequent Acts, and have the final Option or Second tick away in the last Act. That is how the Audience will know a story is over. Oh. Break the Story Limit by changing it or disrespecting it and the Audience will not forgive you.
