I totally understand why anybody would not enjoy, get bored or be uninterested by it since the story takes like 200+ chapters to start unfolding.
For the first 100 chapters you kind of get that filler vibe, that lack of originality in everything, it bothered me in the beginning and wasn't enjoy it as much. The MC also felt kind of emotionless which was irritating.
So in the first 100 chapters there isn't really any plot except gathering the sins so you get that feeling of lack of substance and epicness which starts right about the 100th chapter. So before that you get to know about the characters and some of their backstories to then face adversity where all the epic shit goes down. That's why every single chapter is necessary since it contributes to the understanding of the characters' choices and emotions when you go on with the story.
Now I'm just going to say this, if you don't like ''child-like'' shounens like BnHA or Naruto, then be my guest, dislike this manga and go your way. However if you are a true shounen lover then you will absolutely love Nanatsu no Taizai. I was sceptic about it at first but this manga surprised me, it surprised me a lot. Where it seemed to be emotionless, a sea of emotions was hidden. Where I thought there was no adventure, a rich and masterfully crafted story started unfolding.
This manga is hidden masterpiece.
Just like it's main character, it's not flashy, doesn't try to impress with cool looking characters and crazy battles. Everything about it may seem dull while deep inside it is about to explode with so much richness of drama, action, emotions and story that you're so not ready for.
Nanatsu no Taizai is continuously catching you off guard. Continuously.
It doesn't feel generic, it always tries to surprise you. Even with its style and choices of plot and characters which always make so much sense in the end and never feel contradictory.
It also shows to be a deeply emotional journey as you go on and discover along with the nakamas, their past, their connections and bounds which for some take like 200+ chapters to unfold but are so worth it.
Story 10/10
I already said my piece here and there about everything surrounding the story so.. don't know what else to say except ''brilliant''. Just brilliant.
As said before it takes a while to take off though.
Art 8
The art is great, one thing that I find particularly stunning is the armors, they look insane. I keep getting reminded of Berserk while reading this shit. All this Medieval shit going on really is a sight to see, very impressive looking. Now it's the characters for me that don't look that great, pretty underwhelming. Bad guys or good guys, I'm not a fan of the choice of style overall. Overtime you start liking the characters but at first the art was turning me down a little bit, and it's not the best quality too except for armors and landscapes.
Characters 9
One big point that I haven't mentioned is how interesting the characters are, it's like the complete opposite of Fairy Tail to me where every single character feel corny and generic. I'm not necessarily a fan of the art or design of most characters, they aren't that spectacular and flashy like in Bleach or One Piece but they are really likeable and interesting. You can strongly feel that each and every character has his/her own interesting past and story to tell. That which is completely nonexistent to me in Fairy Tail for instance. There is always that feeling of richness, be it in story, backstory, characters, history and so on. It's the first time that I can sense this feeling of a rich and vast universe and adventure since One Piece. Never felt that since then and Nanatsu no Taizai gave it to me, it says much.
Enjoyment 10
I mean.. it's a blast man. Got totally in love with the nakamas, I really started caring about them and feeling attached to them, there are so many beautiful moment to witness. I like the fact that there is a lot of romance, I'm glad that the author, Suzuki Nakaba isn't ''scared'' to implement romance as most shounen do. I was deeply touched through the romance and there is quite a bit of it, which doesn't obstruct the story but rather gives it way more depth and so more delicious drama.
Also I've been enjoy a lot the bonds between characters, it doesn't feel hollow like they're just a team working together to achieve a goal but rather like a true family that cherishes each like nothing else, it's very beautiful. And there also are a lot a fun and chill moments which are really enjoyable just like when Luffy is on the sea with the Thousand Sunny and everyone, these moments are special and Nanatsu no Taizai does feel special.
Conclusion:
I gave a 10 because I don't see how you can get better than this as far as shounens go.
I'd recommend this mostly to those who enjoy shounens even though I love seinens just as much. I think the story is so deep that some people don't take the time to understand it because it is too hidden, while it might seem dull the dullness itself is like the shell of the story, literally covering its heart. It might take long, but each chapter will pierce through it and reveal more and more of its shining beauty.
I don't make reviews often, just the fact that I had so much to say about this manga speaks for itself.
You beautiful masterpiece.
