What makes people depressed after watching the plot of the synthetic beast in The Alchemist of Steel?

I think The Alchemist of Steel is excellent in both ideological connotation and story structure, and it is a work that everyone talks about. When I first saw it, I was depressed because of the words "night of synthetic animal wailing". My father actually turned his daughter and his dog into artificial beasts. Until now, whenever I recall this episode, I feel sad and angry.

I think many viewers have been abused by this story. This paper will interpret the sentence "Why is this episode so gloomy" from two aspects: "story creation" and "audience psychology". Using many narrative techniques, the author created a beautiful image and personally destroyed it. This is actually the creative thinking of many tragic works. It is very sad for the audience to witness the disillusionment of good things. The atmosphere in the first half was relatively relaxed. The little girl is like her father's little angel, and she is very kind to the Edward brothers. The girl knows nothing about the future. She is eager to continue this life and always hopes that her mother can come back.

In the medium term, the atmosphere became extremely tense, the military pressed hard, and Tucker was cornered. Tucker had mixed feelings when he saw Ed who was qualified as a national alchemist at the age of 12. There are indications that Tucker has hidden a lot from the Ed brothers. The audience had a bad feeling when they saw this place, but they still didn't want to believe that Tucker, as a father, would attack his daughter. But the last thing we want to see has happened. When such an innocent little girl really appeared as a synthetic animal, my heart seemed to bear a heavy blow.

What really destroyed my psychological defense was the sentence in the mouth of the synthetic beast-"Ed, brother ..." In addition, there was my father who did whatever it took to get the result, and my daughter who was guarding her father even when she became a synthetic beast. It is very sad that their attitudes towards each other are so different. In the face of such a tragedy, the Ed brothers, who also violated taboos, can't help but think of painful memories of the past. However, the Ed brothers failed to save their mother when they were young. This time, they still failed to save Nina. The two tragedies overlap at the end of this episode, and Ed's crying conveys this sense of powerlessness and self-blame to the audience.

Dark weather, heavy music, the protagonist's heartbreaking cry, the unrecognizable body on the wall, the psychological defense line that the audience almost collapsed, all kinds of factors are superimposed together, and the violent "chemical reaction" has left a shadow in the hearts of countless people.

The above is purely a personal opinion.
