Okay I know this anime series is technically a prequel to another well known anime, but this is just from my personal experience with it.
Fate Zero was an amazing series obviously, and I think I've classified it as one of my all time favorites at this point. The way that anime ended I thought it was done so beautifully, compared to whatever the hell that ending was for Naruto. Now obviously the story of Naruto was about Naruto Uzumaki and his journey (atleast that's what it was meant to be), but the storyline of Fate Zero was the journey of Kiritsugu Emiya, and let me just say this when you see where his character goes from the beginning of the series to the end you start to have a lot of respect for him as a character. It's nothing like with Naruto's journey whatsoever that just had so much potential only for a load of garbage to get in the way of it which turned into the crap that is it today. Not only that, but as I stated the way the anime (Fate Zero) ends was not only perfect, but you can kinda see how it can be continued.
That is where we get to Fate Stay/Night (Unlimited Blade Works) from Ufotable... Now from my perspective I see it as the story of the next generation because Kiritsugu isn't focus the series either, unlike Naruto and Sasuke who practically steal the spotlight from Boruto, who is supposed to be the focal point of the story and his generation. Instead the journey shifts to that of his child (not gonna reveal any names for those who have yet to see it) and I will just say the amount of impact Kiritsugu has in his child's life is far if not supersedes the amount of impact Naruto has in Boruto's life who can easily be seen as a terrible main characters ever in comparison. The important characters from Fate Zero in Fate Stay Night/Unlimited Blade Works only play a small role because like I said before to me it was the passing of the torch from Kiritsugu to his child and his generation.
Now I know alot of fans that have seen the Fate series have something different to say, but it's just my opinion that's all. Like I said before if you guys haven't watched Fate Zero then you're missing something special because watching that will only enhance Fate Stay/Night Unlimited Blade Works at least when it came to my perspective. Don't get the wrong idea when I say this, but Fate Zero is much superior to Fate Stay/Night Unlimited Blade Works yes, but that's not saying it's kitten by any means. Different is the right word to use when it comes to the tone of both series, and you can come to respect after watching both. However to finally put it simple if Boruto was utter trash before for alot of people, then Fate Stay Night Unlimited Blade Works will only make it worse because that surely happened with me, and I'm proud to to admit to the fact.
What do you guys think?
