Though the Dramatica User's Group arrived at a single storyform for this film, it was generally agreed that the film is very underdeveloped structurally-speaking and that it could have benefitted from serious structural work.
That said, the Storyform it could have been would have these settings:
Change, Stop, Do-er, Logical, Action, Optionlock, Success, Good, Physics, Understanding, Instinct, Ability
-
MC Throughline - Harry Potter
-
OS Throughline - Year One at Hogwarts/Protecting the Sorcerer's Stone
-
IC Throughline - Ron/Hermione/Hagrid/??? (here is where it begins to break down)
-
RS Throughline - ???
The lack of a well-developed and fully explored Relationship Throughline prevents this film from successfully making a Grand Argument.
