Dramatica started out as research project into story telling. It's a complicated theory. The result is a methodology that does a few things right compared to other approaches:
1) Maximizes conflict between characters and across the story's timeline. Although Dramatica can deal with a cluster of characters, the simplest (and IMHO the most comprehensible) form is between two characters.
2) Forces the author to go through character attributes (Need, Desire, Weaknesses, etc.) first and plot comes second.
3) Generates a POV-less and genre-less story structure. There is no Protagonist nor Antagonist and the story structure doesn't enforce - or converges to - a genre. It's like writing in omniscient. The author can decide which character becomes the main POV afterwards. The genre sort of emerges from that.
PROS
- Forces authors to think about characters first along with the conflicts between them. Plot comes naturally from that.
- The line of questions opens up more questions from which you derive opportunities and more ideas.
- Works well with open-minded "I don't know yet what it's gonna yield" type of story development.
- Having been designed with TV dramas in mind, this approach is well suited to developing series.
CONS
- Convoluted underlying theory. If you must know how this works, be prepared to spend some insane amount of time.
- Superficial definitions and interpretations. You have to stretch your imagination to make them fit your story.
- Genre is not enforced. If all you want to write are thrillers, you will curse.
- $$$$$. Some parts of the software are patented, hence the high price.
CONCLUSION
If you are stuck with a character or two, maybe three, tiny story fragments with nothing connecting them, and have no clue where the story goes from there, then this might be the muse you have been waiting for. Otherwise don't bother; it'll be a huge piss-ass waste of time.
Hope this helps.
