Who can explain to me the theme of the movie Butterfly Effect? I don't quite understand.

The film has the most ingenious idea. The most subtle thing about this idea is that it provides us with opportunities to repent again and again.

No one will be completely satisfied with his life. Therefore, the most basic setting of this film, and even repeated assumptions, will bring us a lot of false fantasies and endless desires.

I won't make that mistake if possible. Maybe my life will be better. Under this assumption, we can face an alternative life like the protagonist Evan. If so, what will happen? This imaginary illusion can only stay in fantasy, or in movies. What this movie wants to tell us is that even if there is such an opportunity, everything may not be as beautiful as we thought.

The plot of this film is set in the present, but what can be changed is some important gathering points in the past. The way to change is through Evan's memory of those lost points; After reading the diary I wrote when I was a child, I will come back to remember and build those memories in the way I hope. All the memories will be rebuilt because of this change.

Omitted the development process from the assembly point to the present, and jumped back to the present directly from that point. So what we see in the movie is just like the cause and effect that Buddhists say, except that Buddhists have to go through several generations of cause and effect, all of which happened in Evan's life.

Suppose that the development process of a person's life is a continuous straight line, and this cause leads to another effect, which is closely connected. The conclusion is our life now.

However, if we change what happened at a certain point before, the life changed at this point will change many points behind because of the chain reaction, and more changed points will be rewritten as a whole life. Therefore, the whole life will be completely different.

This is also the most basic foundation of chaos theory in this film. The chain butterfly effect and reality are constantly jumping around with the past. The interlocking and irreversible journey began with this film.

There are endless possibilities in the movie. However, if all these possibilities are mapped into reality and life, the film should follow the proper law of real development to develop the plot, so as to make the countless possibilities of the film plot convincing.

What this film skips is the long development after all these possibilities have been changed. So what we can see is the most direct result after Evan changed all those possibilities.

Causal cycle, this cause is the result, and that cause is the result.

How to choose in the face of infinite possible life? The life after and the life that has become history before. With infinite good wishes, I will revise my life and everyone around me will become better. All our mistakes will be corrected, but will the result be better or not so beautiful?

This may be the ultimate proposition of all science fiction movies that travel through the past and the future.

Einstein's special theory of relativity provides a scientific basis for our future travel. However, in the era of special relativity, the journey to the future is irreversible. We can go to the future, but we will never return to the present. Ten years later, Einstein's general theory of relativity made it possible to travel through the past and the future, and then he put forward the concept of "wormhole" and provided a way to travel. It can be said that Einstein gave us the possibility of building a whole fantasy platform.

To some extent, this film also follows the law that physics cannot interfere with history after Hawking's return. How to avoid the "grandmother paradox" has become the primary task of this film.

In fact, this film has not completely avoided the "grandmother paradox". Although Evan's intermittent amnesia as a child has somewhat avoided this embarrassing situation, Evan's life course has changed because of previous changes. When he filled in his blank memory, his later memories were constantly rebuilt, so his whole life changed, including everyone around him. However, this still falls into the blind spot of "grandmother paradox".

Perhaps, when the demand for science fiction movies is more, we can't ask it to completely follow all the existing scientific basis. Otherwise, science fiction movies may become vulnerable. And anyway, this movie may be farther away from science fiction movies and closer to fantasy.

Science fiction must follow certain scientific principles. Fantasy movies are completely unnecessary. This will also be the reason why this film can become a reality in the film. In other words, we shouldn't ask too much of such films. It is entirely possible to watch this film without special relativity, general relativity and "grandmother paradox". Then we can begin to marvel at the ingenious conception of the screenwriter and the director's proficiency in camera language.

Based on the madness of a perfectionist, what Evan needs to do is to build up his due memory on those vague assembly points. After these memories are established, all his later memories will be rewritten because of the butterfly effect. So his life is constantly being rewritten.

This is also the brain doctor's diagnosis of Evan's disease in the movie: people's memories are stored in the cerebral cortex, and Evan's disease is because after the cerebral cortex is destroyed by oppression, his memory is reconstructed from there, and his whole cerebral cortex is constantly being reconstructed.

This is perhaps the most scientific and reasonable explanation for what happened to Evan in this movie. In Evan's own view, his life can be constantly revised and changed in his own way, while in others' view, he just keeps rebuilding his memory in his own cerebral cortex.

It's just that everything we see is not what Evan imagined. Every time he corrects it, it always makes things worse. Therefore, in order not to let people around him suffer because of their own modifications, all he can do is to go back to all possible modifications before and modify his and his friends' lives again and again.

Will God laugh at you? Nobody knows. It's just that life seems to have unchangeable rules. Perhaps it can be said that we should be grateful for what we have now. Contentment is not about changing what has happened, but about how to change the future life. This is the real truth that this movie tells us.

Everything that has happened, perhaps, every important decision made in life will affect our life. And everything that has been decided before has cast our present life. Perhaps, when God chose for us, he has given us the best way. What we have to do is to cherish everything now.

Ivan's actions run counter to God's path. God is smiling or sneering. No one will know. Every effort to build will only make things worse, but no one will tell Evan until he starts trying to change. Maybe, even if I tell him, he will do it.

Human nature is greedy. The first change really makes things better than before. Of course, someone will pay for it. However, in order to correct the miserable life of friends outside his own life, after Evan finally exhausted all the opportunities, things couldn't be worse.

No one's life is completely beautiful and has no defects. So, perhaps, only by recognizing the existing shortcomings will the world become better, instead of constantly praying for better and more illusory things.

When Evan finally watched the video recorded by his father when he was born, he remembered that he killed himself in his mother's womb. The film showed us many beautiful scenes. After Evan died in his mother's womb, all his friends grew up healthily and lived happily.

Perhaps, this is also the beautiful and illusory wish that the film can finally give us. However, it also caused my reflection. If we had never come to this world, would we? People around us will live a better life.

Being born means changing all other inherent laws around you. So, because of the change of integral, more changes have taken place. This may be the darkest and most terrible logic that chaos theory can bring us. However, from another perspective, the world is actually in a state of balance and harmony. Aside from this film, in fact, for this world, the existence of each of us is an indispensable part of internal balance and harmony.

Because the butterfly effect in chaos theory itself is also an indispensable and important part of world balance, harmony.

As the subtitle at the beginning of the film says: It is said that a small thing like a butterfly flapping its wings can cause a storm that sweeps across half the world.

Because it exists, it is reasonable. This is itself a part of this harmonious world.

How should we choose our own life? Everything before has achieved everything now, and the only thing we can choose is the future. A little thing like a butterfly flapping its wings can actually change our future life.
