What is the screenplay paradigm?

Answer 1

The Paradigm here most likely is attributed to Syd Field who applied Aristotle's Poetics to screenwriting and used it as a model for the three-act structure. Act 1 set up, inciting incident, and plot point 1 - which moves us into act 2 the middle of the screenplay - the midpoint- is another crucial demarcation point that shifts us into the second half of the movie. The end of the second act - plot point 2 - is another turn or twist which moves us into act 3 act 3 contains the climax, obligatory scene (where "it" all goes down) and finally some sort of statis or resolution that leaves us with a satisfied conclusion
