Aristotle didn't invent the 3 act structure for drama. He merely made an observation after studying great stories; that every great story has a beginning, middle, and end (3 acts, as they later came to be called).
You can call them anything you want: hero's introduction and inciting incident, rising tension, and climax, etc.
Who cares?
EVERY dramatic story you tell, if told well, will comprise 3 parts, or acts.
You'll see various variations: 4 act (where the 2nd act in the 3 act structure is merely divided into acts 2 and 3), 9 act (where each of the 3 acts is now divided into 3 subacts), 12 act, 5 act (I think USC's MFA program teaches 5-act structure)...ad naseam.
It's all the same. But, some writers like to conceptualize the 3 act structure as smaller acts in order to help them better craft their story; it helps them to keep the tension of the plot points and story beats if they can subdivide them. Use whatever works.
If you write a good, well-crafted story, it'll follow the exact same bell curve that every great story does.
Beginning, Middle, End. You can plan, study, and manipulate the nuances any way you wish.
However, be mindful that traditional "three act structure" is the "language" of Hollywood.
So, if you ever get a meeting with the studio big whigs, or producers, or whatever, you'll need to understand the 3 act structure merely to be able to communicate your ideas to them effectively when articulating/discussing your story.
Sure, you can write your story any way you want (3, 4, 5, 6, 9, 12, 120 acts...even though they're really fundamentally all the same), but when you're ready to sit down and talk to the people you need to talk to, you better be able to translate and articulate your "4 act vision" into the "3 act language" of Hollywood.
You'll often hear some wannabe "writers" whine about the "constraints" of the 3-act structure, or how it's "obsolete." 99% of these people are just crappy writers who are incapable of writing an effective story, therefore they blame their lack of talent on the 3-act structure, rather than the fact that they suck.
The remaining 1% who whine about it are just weirdos with delusions of eccentricity and supranatural insight.
So, 3-Act structure isn't a "type" of dramaturgical model; it's THE model. It doesn't limit or inhibit or constrain your story in any way. The only thing that limits or constrains your story is your writing ability....or lack thereof.
You'll find that if you write or read a great script and then analyze it, then it'll follow the 3-Act structure nearly perfectly (or 4, or 5, or however many acts your mind divides it into). Beginning, middle, and end.
It's just the natural, organic existence of drama.
3-Act structure is a way of analyzing great stories for discussion. It's sort of like versus in the Bible. They were only added so pedants could reference the passages more quickly in order to better argue about them. The Bible already contained passages and sections and sagas. Versus and chapters were merely added in order to better study the contents.
Same with drama. Every great story contains the same elements. 3-Act structure is merely a model which most accurately allows those elements to be discussed.
