Manga, of course, is not a masterpiece. Just a good shonen. The ending is not so bad, but compared with all the potential inherent in the manga from the very beginning is definitely a profane.

But just many points have not remained uncovered.

- The main antagonist and his motives in comparison with other demons are not understood at all. The most powerful demon, who also lived a thousand years and so merge everything at the end, turning him into another cached villain, a la miserable - I am afraid of death and the only purpose of my life is to become immortal and invulnerable.

- The arch with the final battle caused an ambiguous impression for me. Even the deaths of many characters seemed only as death for the sake of deaths and an unreasonable tear-extractor, and with all this, all this praised power of Muzan was never felt. The same battles with the higher moons and other demons like the spider boy, in my opinion, were much more epic.

- Many characters have not been revealed. With the main trinity and Nezuko, everything is more or less good, but nevertheless, for example, the disclosure of the other pillars was still not enough.

- Most of the plot twists have seemed to me just like a useless tear-jerker.

As a result, the manga is pretty good, like any other, it has its pros and cons. It does not touch on any serious philosophical issues; this is not bad, but not good either. It is worth reading, but even among other shonen, it did not become the best for me.
