Hah! Funny list.
That’s the funny thing though — I don’t think, objectively speaking, that efficiency or effectiveness factors into narrative structure. I can see from an Audience Reception context it might be important, but Storyforming not so much.
The reason I asked about Zemo’s connection was because I wondering if I missed something the first time I watched it and he was somehow involved in it, which would mean you might have a valid point with this:
Except what does setting up Bucky as the one who set up the bomb really have to do with the story goal of ending the Avengers in order to end the inequity introduced by Scarlet Witch?
As you mentioned in your other thread Zemo is just taking advantage of the situation. It’s like Luke in Star Wars, he’s not taking over for Leia as Protagonist in the Overall Story to fight the Empire so he can specifically stop them from illegally boarding ships. It’s just that there is an Inequity, a Goal for resolving it, and Luke focuses on the Goal—not really thinking of the Inciting Incident/first Story Driver.
It’s not that the Goal solves the first Story Driver—it solves the inequity creates by the first Story Driver.
