I personally like this filler, because it focuses on what could have happened in a different way, but ends in the same result
If Obito, would have died in that accident, then Madara would have moved on and chosen someone different, and the kyuubi attack would have never occurred Naruto parents would have never died, The Uchiha clan would have never been discriminated against but.......
The Akatsuki would still exist, but this time Naruto and Kushina would be hunted down. but in this filler it's just talking about testing the younger generation, and it was obvious from the beginning that it was Neji's father
I actually want this story to end, so the producers can get through all the side stories they have plan, but the only side/actual story I want to see is Hinata's
