It doesn't have a storyform because it has three!
But seriously, thinking back to the movie, I'm with @decastell in that it seemed pretty standard and didn't feel as though it would be lacking a story form.
On a side note, I've always wondered about this:
In stories that reflect Western culture - particularly in American culture - the Story Goal is traditionally found in the Overall Story Throughline. This results in a story in which the Goal pertains to all of the Overall Story Characters. The Goal, however, might just as appropriately be found in the Main Character Throughline, or either of the other two. In such a story, the overall Goal could appear to be whatever the Main Character was hoping for or working toward, regardless of what was of concern to the Overall Story Characters.
I'd sure like to see an example of this...
