Well, this is a tricky one... There's not much to say, I'll just give the score and then my opinion which I believe is the most important in this one.
Writing Quality: Absolute Beast, almost no grammar mistakes. 5 stars.
Stability of Updates: Great Stability, cliffs won't be kept for long, The author is serious... 5 stars.
Story Development: Totally Brutal. Once you start reading this, unless you have a big will, you won't stop. I don't know what kind of drug this author made but it cost me a lot to leave it... 5 stars.
Character Design: Infinitely Mad... The MC is just a beast, nothing else to say here, all of the characters in Naruto stick to their own character perfectly, 5 stars.
World Background: Naruto before everything began... The author sticks to the events perfectly but he doesn't follow canon, at least not fully.
Now my opinion: Phew, man I will be saying that I dropped this one... But I didn't drop it because it was bad, but because it was going against everything that I represent as a person. This fanfic is fking good! it is like you're watching Game of Thrones, you can spect anything to happen here. So the uncertainty of the story is there, basically, this novel, if it can be called that, is everything but cliché, therefore, making it so that you don't know what will happen next to be it good or bad.
As for why I dropped it. MC is simply too Evil for my tastes. Believe me, I can tolerate an Evil protagonist but this is just so far beyond simple Evil. I mean using his own mother as a hidden card in case somebody wants to go against him? Sorry but I'm someone that loves my mother with all my heart and I felt nauseated with that.
There are many inconsequential things. First, I believe the background story of the MC is too shallow for his actual personality. I can only fathom somebody having that kind of personality in either of these cases:
1.- He's an Alien being that somehow got killed by the army of earth and got reincarnated by god as a human in Naruto, his hatred for humanity made him the way he is.
2.- He's a cultivator that has lived for thousands if not millions of years trying a trying to length his life further to be able to keep living, that would make him so desperate for survival that it would explain his behaviour.
For those who read it and think it is ridiculous, then imagine just how Evil the MC is...
*Spoiler ahead*
My breaking point was Tsunade's situation. The fact that she didn't outright kill their child because she thought it was Dan's stung in my heart so bad that even in my working period I was thinking about it...
Another thing is the fact that he supposedly thinks a lot of his previous family, that's so stupid to me, a person that behaves the way he does should not have someone they appreciate in their heart. Because one of the principles of Love is Gratitude and that's something this MC doesn't have at all. I mean his second mother might not be his real mother, but that doesn't change the fact that she gave everything to him until he grew, and that she gave birth to him as well. She could have just been a ***** of a mother and abort or simply throw him away and he might have prevailed but his path would've been way harder.
I would keep reading this novel if I had some certainty that MC is gonna change his ways, but the way I see it, which I can actually foresee what's gonna happen with his son, I just don't want to read that outcome.
I would have hated this series if I was a diehard Naruto fan, who'd like their favourite characters used as tools?
Whatever, I give this fanfic 5 stars because as I said it is perfect in almost any sense. For those who are into this genre, it will be the perfect story but it just isn't for me. For those who like a Light Yagami post-L's death then this is for you, I can guess the author took a lot of inspiration from there.
