I started to read this manga quite eagerly, its first chapters caught my attention because of its medieval fantasy universe, at the time many compared it to Fairy Tail, and although I think Nananatsu No Taizai is a little more superior, the pace Natnatsu No Taizai took in his last sagas was disappointing, until his endless, meaningless, boring and anticlimactic end.
Nanatsu No Taizai tells us the adventures of 7 famous and powerful knights, who one day are betrayed and blamed for something they did not do, because of this, they separate and now they must reunite to save their kingdom again. The premise of Nanatsu No Taizai although it was not something totally original, the way in which the events were happening was interesting, since all that atmosphere of magic and of the medieval time was very entertaining.
However, one of the big problems of this manga are its characters, specially the one of its main protagonist: Meliodas, since it is the first time I read a manga, whose main protagonist is a bad character, badly developed, without any kind of charisma and who repeats the same joke over and over again, besides always presenting him as the most powerful of all, and that in principle is not a bad thing, but being a quite flat character, who really doesn't have a level of plot depth, makes Meliodas, one of the worst protagonists of Shonen.
Characters like Escanor and Ban (part of the 7 deadly sins) play a better role in the story, since you get to empathize with them throughout the manga. They are characters with great charisma and personality, who even among the fans of this manga, are more loved characters than the main protagonist himself. And that secondary characters, with relative importance in the manga, are more popular and loved than the main character of the play, that is a sample of how badly built this character is.
Over the years I have read 3 mangas of which I have liked very much, but whose endings have been disastrous. Two of them I mentioned before, Naruto and Bleach, and Nanatsu No Taizai is the 3rd manga that has disappointed me the most because of its lousy ending. One of the aspects for which Fairy Tail was very criticized, is the so called "Nakama Power" which consists in the group of friends joining their powers to defeat the villain of the moment, or also a group of friends gives encouragement to a character to "magically" and illogically due to the plot, defeat the villain. Nanatsu No Taizai even though on some occasions he had that same problem, it was not as evident as Fairy Tail, however, in the last saga this became something recurrent, reaching absurd and annoying levels.
And while we're on the subject of the last saga, I've previously said that Bleach lengthened his last saga too much, with endless, boring fights (on some occasions). But Nanatsu No Taizai far outdid it, the last fight with the main villain (or the one we thought was the main villain) was endless, boring and anticlimactic. The villain that we all thought would be a challenge for the main characters was only a character that was getting stupider every time and had an even stupider defeat. But as if that wasn't enough, he wasn't the last villain to be beaten, as another villain, who came out at the last minute, and who came out completely out of nowhere, as there was never a concrete indication of the resurgence of that villain, was really the final villain of this manga, it really was a nonsense, but this new and last villain, for the only thing that he served is to shape the next manga that would be a continuation of Nanatsu No Taizai.
Actually Nanatsu No Taizai was a very disappointing manga, with a horrible ending, with a lousy character development (except for a few), with a pathetic and flat main character, and above all with an adaptation to the anime, whose last season was disgusting.
At least this manga has a good drawing and with great details, really good and original designs, but in short, Nanatsu No Taizai is a disappointing manga.
