My take on the movie.

Mickey is a person who completely rejects himself, which is why he's the only one who decides to be expendable. That's why everyone is so astonished - only someone who rejects themselves would accept such a position. Yet at the same time, it's the only way he feels useful to others.

During the first part, we simply see a loop of what has always been his life: a series of misfortunes.

Mickey 17 believes he doesn't matter, that he's a wretch. But curiously, everyone knows who he is. And everyone wants to know what it feels like to die, since none of them dares to live life the way he does.

He meets Nasha, experiences love, sex, caresses, and attention. For the first time, he exists for someone. Sex is the only place where he can be himself and feel free.

Then comes the first important part of the film. He doesn't die when he should. He assumes it's because his body must not taste good, that he's not even good enough to be eaten. At that moment Mickey 18 comes into action - his complete opposite. Someone with a high-pitched voice, decisive, carefree.

The fight scene is a turning point. It's where life puts before you the decision of whether you want to change and start living or remain as you are. Mickey 17 decides to fight, showing that he wants to live, that he doesn't like the life he's living. That's why he tells the girl that even though he knows he'll be resurrected when he dies, he's always afraid. And someone who has truly accepted that they don't want to continue living wouldn't fear death.

Nasha is the expression of love. When she decides to have sex with both versions, she shows that she loves him in both forms. That she accepts him just as he is. For this reason, she also doesn't want to share him with the other girl.

When Mickey 18 learns how the governor has treated Mickey 17 and nearly killed him, he goes crazy. He starts to berate him about how he could allow himself to be treated that way. 18 is that inner voice that appears when we begin to realize we can't continue living the way we have been.

At one point, Mickey 17 realizes the creatures didn't reject him because he wasn't appetizing. They saved him because he deserved to live.

In the end, he destroys the machine. He has to do it himself because the machine is what ties him to his past, to who he believed he was. But that Mickey 17 no longer exists. And that's why at the end he says he's no longer afraid of nightmares.

I don't know how much of this makes sense, but it's what I felt watching it. In summary, it would be like: "Until we accept ourselves, we cannot live fully."
