Antagonist - Protagonist

Make it clear what each WANTS.

And don't forget that each has a  WANT and a symbiotic CO-WANT

In other words, a WANT and a NEED
In other words, a WANT and a MOTIVATION

The WANT revolves around a person, place, or thing.
The CO-WANT revolves around a person place or thing.

One character says, "I want to put up a picture of my dead mother."
Another character says. "No.  There will be no pictures of her in this house."

That's WANT

Here's CO-WANT
One character says, "I want people to remember her when they are here.  She was a strong woman and made us who we are.  I want to keep that dignified personality alive here."
Another character says, "I want people to forget about her.  She was a bitch. I want to let loose in the house and not think of her looking over my shoulder."

1) Picture of mom
2) Loose Personalities vs. dignified personalities

And the CO-WANT should suggest a relationship conflict BEYOND the protag and antag.

three villains in feature films

Jaws - mayor, quint, shark

Feature films are long.  And to support each side of the "argument" there will be multiple characters.  I think you can find three villains of different power/style levels in a lot of films.

And a lot of times there is a relationship being tested with one of these villains.

antagonist, villain, bad guy

The antagonist wants the same thing as the protagonist in general.

The reason we dislike the antagonist is because they are trying to suppress the want in the protagonist.

They are essentially saying look i want the same thing but i want it for myself alone.
While the protagonist essentially say I want it, and you want it, why can't we share it.  we can't we all have it.

who doesnt dislike a hypocrite?
