First of all, I will focus on all the good things The Promised Neverland has going for it, before focusing on the negative, and why it's impossible for me to lower the score under a 7/10 despite it probably being undeserved.

First of all, the themes touched in The Promised Neverland throughout the whole series are incredibly deep and interesting. We get subtly introduced to the eternal moral dilemma of whether humans are truly more deserving of life than the animals we eat through a gruesome psychological thriller that presents us a world in which humans are no longer the dominant species but instead part of the cattle. That main central theme is never abandoned in the development of the story, and sometimes even discussed among the characters themselves, with things like Emma questioning if it's truly fair to hate the demons when they only need to eat humans to survive. There's also the theme of what happiness is and how we can achieve it among pressuring circumstances which is extensively explored in TPN. I could talk for hours about the opposing philosophies of certain characters regarding this topic, but let's just keep it simple.

Speaking of characters, I think every single main character in TPN is extremely well done. None of them fall flat and they're very interesting to follow as you see how their view on the world evolves, and how much they change along the story. The one exception I can think of is the Goldy Pond crew (minus Yuugo), which, despite being enjoyable characters that you can very much grow to care for, none of them get truly fleshed out, which is indeed a bit disappointing.

Now, regarding the biggest point of controversy when it comes to TPN: its story. I absolutely loved the Escape Arc, and on itself it could be a solid 9/10. However, sadly the manga does nothing but slowly fall apart from that point onwards. A lot of people call the Goldy Pond Arc the best arc in the series, but I honestly could already see a few pacing issues starting. Nevertheless, despite these pacing issues weren't bad enough to heavily impact the story... until the final arc. Not only is the pacing in this arc unbelievably fast, but also there's a lot of suspiciously convenient moments that make the plot lose impact. The resolution of the entire series (spoiler: Lewis abolishing the farms) came out of nowhere and went against his previously established character in a way so sudden and brutal that it was nothing but disappointing. However, I will say the ending of the series (spoiler: the whole thing with the cattle children travelling to the human world) was very sweet and managed to make the mess of the final arc feel less bitter to me.

All in all, I am unable to punish TPN with a low score because I have a lot of appreciation for the earlier arcs of this manga, as I believe they present interesting ideas and do a proper level of analysis on heavy topics, as much as they can manage as a fictional story. It is true, however, that the ending of the series feels like a low blow and although it wasn't enough to hinder the love I had for everything already seen in the story, I can perfectly understand how it can heavily affect the enjoyment of others.
