I found this to be a useful book which re-alerted me to the importance of not losing sight of the essential elements of the story, especially the specificity of the issue to be resolved, when one is down in the trenches of the intricacies of the story, that may be developed via Dramatica. Intricacies that, when finessed into place, too quickly become an end themselves. It was interesting to note that Dan did not do an analysis of the Alien that he wrote. Which, although substantially similar to the Ridley Scott movie version, neither of them conforms to Dan's dynamic structure, as I understand Dan's dynamic structure. By contrast, the James Cameron movie sequel, Aliens, does.
The Alien that Dan wrote, and the variation that Ridley Scott directed, is based on rhetorical repetitions that build to a dramatic climax of options. Dan's criticism of Dramatica (and I am not an advocate for Dramatica, even though I do use Dramatica), is somewhat cursory. The Alien that Dan wrote, is a fundamental piece of Sci-Fi, as in the literature of an idea for a monster that is distinctive and distinctively different to the Vampire, the Predator, the Werewolf, for example, that did not require much in the way of development, as per the dynamic interplay of the story and characters' dynamics. Aspects of story that Dramatica does help to develop and guide one, to keep consistent. It should be pointed out that the original Predator follows a similar form to that of Alien, which is probably why it was that Predator did not WOW the critics, on it s release.
The Ridley Scott version of Alien, did try to fatten things out, beyond the appeal of a straight Sci-Fier, via an emphasis of the characters' interrelationships and their relationship to the company. I felt that this was rather overly done, via the whining of Parker and Brett, and one could conclude that Alien is akin to an industrial dispute without the option of arbitration, with the Alien acting as the company's unstoppable, union-busting enforcer.
Dan's dynamic structure will help to make it more likely that the story will work. Yet the writer needs to be mindful of how their workable story, may face significant issues, when it comes to broadening the appeal of their story. A phenomenon that is a challenge for many other stories. For example: Predator, The Verdict, etc.
