Some Spoilers Warning

Story: 10/10
Welcome to Grace Field House, an orphanage run by a "mama" named Isabella. Taking care of 38 loving children, she tests their intelligence through challenging tests where three special kids shine: Emma, Norman, and Ray. These three intellects find out that they are living on a farm where they are raised just to be fed off to monsters. They then have to devise a plan to escape, but many obstacles stand in the way including tracking devices, a new adult to guard them, and traitors.
Characters: 10/10
The characters of the story share a special bond where they can just escape with only a few of them, but they love each other so much, they are willing to take the risk of dying just to save everyone else. The three main characters especially are willing to do anything for each other as Norman is supposedly dead by the end of the story. However, the plot twists of the story may show that he is alive, though only manga readers know.
Art/Animation: 10/10
The art and animations are beautiful. Period.
Sound: 9.5/10
The opening is amazing along with the soundtrack of the anime. However, my one problem with this whole anime is that I do not believe the opening fully portrays the anime.

The Promised Neverland is a complete masterpiece. Every single minute is full of suspense and keeps you at the edge of your seat. The relationship of the children is very heartwarming as they are willing to do anything for each other. Another thing I found great is that everyone's strengths are brought out. Ray, Norman, and Emma all are geniuses and devise plans to escape. Don is not as smart, but because he was brave, he was able to discover the secret room. Isabella and Sister Krone, the antagonists of the story, are adults who are being forced to raise children to be eaten just so they can stay alive. While selling children of their own species may not be the most heroic deed, because they have to in order to save themselves, it is hard to completely hate the antagonists of the story. Also, the plot twists are very surprising as we find traitors among whom we may not expect. This leads to how Ray's backstory is shocking for the audience. Unlike the other orphans, he finds out about the secret of the orphanage early on in his life and had to become a spy. His story is both touching and tragic. Last but not least, the symbolism makes the show deep. Both the flowers and the clock make watchers amazed. The flowers are real objects that play an important role in the series, but they are also symbolic. These white flowers turn red as they drain the blood from those who are taken by the demons. They're a symbol of innocence being corrupted, which is one of the main themes of the story. Meanwhile, the clock that appears throughout the series helps the audience understand the fact that the kids only have a limited amount of time in which to escape. These symbols are easy to understand while also being visually and thematically compelling.
