This year I was a reader for a prominent screenwriting competition. My absolute favorite script in the hundred that I evaluated made me ponder this very question. The script was extremely powerful and meaningful to me, and I noticed that it went on to place high in the competition.
The script employed a Hero (Protag + MC) who spent the course of the story planning and pursuing a horrible terrorist act. While there were character elements of hindering and deflection at play in the story, this Hero more or less proceeded along his path with little impedence. Specifically there was no clear Antagonist elements represented, nor was there an Impact Character.
Because of these important and seemingly missing elements in the narrative, I assumed per Dramatica that this was simply a Tale.
However, the story resonated deeply and left quite a strong and meaningful impression. In other words, it felt like a full meal – more than just a Tale, at least.
So it got me thinking along the lines of this thread’s question. This screenplay left some major structural and thematic pieces out, but still managed to work. Did I fill the missing pieces? Did I draw the “fourth side of the square”?
Because of the horrific terroristic pursuit of this Hero I was on the edge of my seat while reading, effectively screaming at the page for him to stop and for him to change. In other words, I as the reader was (trying to) act in the capacity of both an Antagonist and an Impact Character. Of course, I was entirely feckless in these roles because I was the audience, I was on the outside of the story, unable to impact, unable to prevent – so the Hero of course remained Steadfast (to my frustration) in his evil pursuit.
Not sure if this writer knew Dramatica or not, but he seemed to have strong command of his craft and must have known he was manipulating craft conventions.
