Since there isn't much I can do except reread the script over and over, I decided that there was a noticeable lack of meat to the middle of the story. I'm currently scripting two whole new scenes that add a little exposition and some much-needed character development.
While reading, I had the thought that the script seemed in to much of a hurry to get to the ending and because of that the ending didn't have nearly the impact I want it too. In addition, the timeline itself felt far to compressed. I could imagine that there just wasn't enough material for the viewer to grow attached to all the characters, so I figured out where the gaps were in the character's emotional journey and timeline, and made plans to insert two entirely new scenes.
The first scene is a dialog/suspense scene taking place in the northern Hinterlands, and in addition to filling in a gap in the story, this scene will reveal the first foreshadowing of where the plot of The Thaenor Chronicles is going in its future installments.
The details of the second new scene are still a little unsure. My thoughts are that it will be a small bit of visual exposition, probably involving a flashback or two to show some of what took place during the three years between Chapter One and Chapter Two. What exact form this will take, I can't say yet.
I am now approximating the running time for The Thaenor Chronicles - Chapter Two, to eventually be somewhere between 25 and 30 minutes. Of course this is only a rough estimate.
