Human nature has always been gray. Black and white can be reversed in a single thought, and right and wrong can be overturned in an instant.

I remember that a movie "Train to Busan" was staged last year. After watching it, I seemed to understand a lot!

If someone tells you recently that a zombie movie made you cry, don't laugh at his courage, and don't doubt his tears.

You will know after you test it yourself.

This zombie movie called "Train to Busan" has been watched by more than 80,000 people on Douban, with a rating of 8.3.

The story is very simple, zombies invade and bite everyone they see.

On a high-speed train from Seoul to Busan, passengers who are threatened by zombies face a last ditch effort on the edge of life and death.

At first glance, the theme of "Train to Busan" is purely curious, but the closed environment of the high-speed train increases the level of danger, and the journey with a beginning and an end intensifies the tension.

But these are by no means all the reasons for the popularity.

The biggest advantage of "Train to Busan" is that it uses imaginary monsters like zombies to prove the horror of human nature in reality.

The following contains spoilers.

Suppose one day there are zombies on the train you are riding on. How will you deal with it?

Risking your own life to protect your family?

Join hands with passengers to fight against the enemy?

Preserving yourself first at the expense of others?

In "Train to Busan", everyone is there.

The fat uncle is the light of mankind. Not only does he have incredible fighting prowess, he can fight zombies with his bare hands, and he never forgets to save children first when in danger.

In the end, it was his sacrifice that ensured the temporary safety of his pregnant wife and other passengers.

The high school students on the baseball team have a gentle personality and are forced to defend themselves. They are unwilling to abandon their friends on the platform. They still can't take action when they see their teammates turning into zombies on the train.

The company executive, who was disliked by countless people, first tried to use his power to escape privately in the front of the train, and then organized the passengers in the train to stay on guard. In order to seek temporary safety, he put the escapees in danger.

Later, the executive simply turned completely black and pushed the flight attendants and female students into the zombies' mouths just to find a way out for himself.

The driver came to rescue him, but he escaped by himself, regardless of the driver's life or death.

The only twist is that when he transformed into a zombie, he muttered: "Please take me home. My mother is still waiting for me at home." As for the male protagonist, he is a fund manager who has always been self-interested.

Tell your daughter as soon as possible to take care of yourself first, and it is best to leave first when encountering a crisis.

For this reason, I almost got beaten by the fat uncle.

But as the crisis intensified, the male protagonist began to fight side by side with the fat uncle and high school students, letting the homeless man with handicapped legs go first, obeying the fat uncle's instructions, and desperately protecting the fat uncle's wife.

Finally, during the duel with the executive, he was accidentally bitten, and there was a shocking scene of jumping from the train.

It is difficult to evaluate whether everyone in "Train to Busan" is small or great.

More often than not, they are a compromise between the two.

As an audience, you may have a strong sense of justice, angrily complain about the executive, and praise the fat uncle.

But if you really want to be in it, who can guarantee that you will definitely show bravery and selflessness.

Human nature has always been gray. Black and white can be reversed in a single thought, and right and wrong can be overturned in an instant.

What impressed me most was that when the high school girls learned that their boyfriend and other passengers were expected to pass through the zombies from other carriages, they were so excited that they couldn't contain themselves.

The executive clearly opposed it, and encouraged the conductors and other passengers to stick to the fence.

Even if there is only the last door left, they are still fighting to the death.

If routine is the source of evil, then the hesitant passengers in the same carriage are accomplices.

If you think about it carefully, to a certain extent, we are not necessarily fat uncles, male protagonists, or high school students, but more like these numb, selfish, and wavering ordinary people.

Fortunately, we did not contract a zombie virus in a special situation.

Extreme situations amplify human nature.

And human nature often cannot withstand scrutiny.

In "Battle Royale", my favorite is the couple who committed suicide at the beginning.

In "Titanic", what I envy the most is the violinist who remains calm in times of danger.

The former is based on mutual trust and sacrifice, while the latter is based on the unremitting persistence of faith in life.

Unfortunately, this case does not belong to the majority of people.

In the adult world, there is no simple good or bad.

The so-called human nature is nothing more than the struggle with one's own heart.

Although we hope that we are the indestructible fat uncle and the hero who has been transformed and reborn, the fear, helplessness and hesitation of ordinary passengers are more likely to appear in us.

Compared with absurd zombie stories, the real black hole of human nature may be more terrifying.
