The thing chain saw man those really well that people here are really talking about is visual story telling.

During the movie scene where makima cries, the scene shown on screen is simply to characters who clearly know each other hugging. this not horror, or comedy or action or anything else is what moved makima to tears.

This seems like a small scene but when you think about it with the context of the ending, what makima really wanted was a friend, but since she was the devil literally born to subjugate others the only creature she could possibly have an equal relationship with was a creature that couldn't be subjugated, the chainsaw devil. Makima imagined the chainsaw devil to be this completely wild untamable force of chaos because deep down that's what she needed him to be so they could actually be equals. Because of makima's desperate need for the chainsaw devil to be this wild monster she could never actually realize what he really wanted or needed.

when her reincarnation appeared Denji asks how to give makima that relationship she deeply wants and Pochita says "lots of hugs".

This is powerful because of who is saying it not what is being said Pochita is the chainsaw devil and he is showing deep empathy and understanding to Makima inspite only ever fighting her in hell.

this is wear the movie scene comes in because Pochita inspite not being visually present is watching the world through denji's eyes. he also watches the same movie sees the hug scene relates to the movie as another devil who's true goal was companion ship and realizes the makima is similar to him in that regard.

Makima set up the whole date to manipulate danji with the goal of getting to chainsaw devil yet ironically her showing vunerability and crying at the movie is not only the closet she has ever been to the chainsaw devil emotionally but it is also everything she thinks the chainsaw devil is not.

One layer deeper than this this movie scene happens during the reze arc and this is important because again ironically enough reze and denji hold a similar relationship to pochita and makima.

reze ultimatly falls in love with denji because she relalizes that their similar people at heart but denji refuses to run away with her because he is still caught up with the idea that what he needs is a place to stay, food and and sexual fufilment. (everything makima is promising him) rather than deeper emotional intamcy and care what he really needs.

Pochita in the movie scene must have had a similar realization to reze except he also realized that makima would never be able to to be a companion for him because she is still caught up with the idea of needed to be equals with a force she can't control rather than deeper emotional intamcy and care what she really needs.

Its funny because once you realize this parallels you also realize that by extention makima and denji are also very similar characters with very similar needs and very similar misconceptions about reality which they both refuse to let go of.

Makima believes she needs this equal she cant control because she is under the mistaken belief that as the devil representing control she is incapable of truly connecting with someone weaker than her.

Denji believes he needs basic neccesities and sex to be happy in part because of Makima's manipulation but on a deeper level its because he is under the mistaken belief that he doesn't deserve a family or deeper levels of intamcy outside of sex due to his relashionship with his father (those who know know)

Both realize their mistake atleast to some degree with the birth and subsequent family dynamic of nayuta.

its also funny because denji is actually more like the vison makima has of the chain saw devil that pochita is (every time we see pochita fight he is actually shown to be very careful and intelligent, by contrast denji's fighting style is way more chaotic and beast like than the chainsaw devil.) but she can't see that due to her delusions about power

and again the parrallels because reze is more similar to the vison denji has of intamcy (sex feeling better the more you know about and care about the person) than makima is but he cant really see that again due to his delusions.
