Because of all the negatives I almost didn't watch this, because all you see is that the story is predictable or stupid, and the list goes on and on...
But let's be honest, what anime is not predictable? I don't know about you guys but there was not a single anime that I was unable to predict or at least parts of it, I always think about it while watching it and guessing what's gonna happen which is just like an instict to me, Im not even trying, and Im almost always right. So what if you may guess who is gonna die in the episode? So what if you can guess who is going to win? Is that really that big of a deal? But I really doubt there is a single person who could say HOW the person was going to win. That was not predictable at all, it was greatly made and it all just made sense in the end, not beforehands. So yeah, you may find yourself asking why this one had to die like that, or why does that one win, but the end makes you say, "ah", because everything just HAD to happen that way and that makes it wonderful... that there was a really good reason why did everything happen the way it happened. So even if you hate that your favorite chars died, or how they died, in the end, at least in my case, I was like "oh okay" and the bitterness fades away, because it just makes sense. And thats one of the reasons why I like this anime so much, because only few anime have that.
Even tho Im a fan of Fate/Zero, I don't like the others like Fate/Stay night etc, and Juuni Taisen has what I liked about Zero. There's action, there's blood, there's story, there's different and likeable characters, there's no room for teenagers and their drama - and especially there is a simple ending - one winner, and not just like any other anime that just ends whatsoever. Simply its one of the good ones. Sure, everyone has their own opinion, but don't be stupid and let the haters ruin the anime for you when you haven't even watched it yet, make your own opinion and reasons why you hate or like it. Give yourself a chance to watch it without being influenced.
The only thing I disliked about this anime was that every character had their background explored but one. And I kinda hated the 9th episode, haha (especially the animation, since the whole anime had this really cool animation, but then in that one episode it was like playing some game, it was really disappointing, but it eventually got better again, so yay)
So yeah, I like the story, I love the characters, in the most episodes I loved the art, the music wasn't that memorable tho but I enjoyed the whole anime to the fullest.
