I wouldn't think of it as ignoring anything, but I would spend a bit of extra time focusing on the things I mentioned until you understand them.
Rewatch a favorite movie or reread a favorite book. What is the mood at the end of the movie? What is the mood of the Main Character? and, importantly, how do you know?
Example: At the end of Star Wars, Luke, Hans and the Wookie all get medals in a ceremony filled with pomp and circumstance. They all seem happy and they are smiling with each other.
You don't need to know much about the rest of the movie to know that this is a Judgment: Good.
There are rare stories where it is not this obvious, and if you read or watch something where you don't know, just skip it, or ask here for guidance. Find ones you recognize, and build up from there.
This moment is usually not subtle. So once you begin to recognize it, it is pretty easy to incorporate into your own work.
A bit trickier, but usually by feel you know if a movie is a Success or a Failure. Again, you must be able to point to why this is true. The feeling will guide you, but then you have to back it up with facts. This means you have to find the OS Goal, define it, and see if it's been achieved.
Example: In Lord of the Flies, the boys want to attract the attention of the British Navy. Specifically, Ralph wants to do this and he is the Protagonist. Last Chapter: The British Navy comes to the island. Success.
I like this example because, even though Ralph is the Protagonist, he is not the one that brings about the Success ending. It does not matter who makes it happen.
Ask yourself "What happens at the beginning of the story that forces the story to happen?"
Ask yourself, "What happens at the end of the story that lets me know it's over?"
See if you can start to recognize Actions and Decisions at these two moments. (There are more, but focus on these two.)
The forces is important. I can decide to become a lawyer in the first scene of a movie, but if an flood hits my city and the movie is about saving people, then you know that my decision to go to law school isn't relevant to the OS. Maybe it's relevant to my MC thread. Maybe it's filler.
Okay, this is the hardest one on the list, but it's the beginning of deep knowledge.
1. Listen to the podcasts. Watch the movies, and then listen to the first 30 minutes. You will hear how we sort these out. We ask questions, basically: "What is the overall story?" "What is the the MC's personal problem?" Then we put them into the four domains. Learning to see these, like all things, just takes practice. Rest assured, this is easier in a group, so if it's hard doing it alone.... well, yes, it's hard doing it on your own. That's just the way it is.
2. Make up stories you never plan to write. Do this on your own or with the Brainstorming button. Come up with an OS, MC, IC, and RS. Make sure you are making them discrete. (Non-overlapping.) Practice, practice!
When you have questions, start threads, and ask away.
