Ever since they introduce the Sage of the Six paths who was revered to be a god, Naruto series has been on the path of Godly feats. I don't think that's a bad thing though as long as there are still some logic behind each characters strength and power ups, such as using tailed beast chakra for OP attacks or Chakra absorbing mokuton for unlimited supply of chakra and speedy regeneration.
In the beginning the action was so fun and it was innovative. It was so different from what we were used to seeing. Now its just like any other anime. Kamehameha, Big bang attack, so lame.
I will admit they were always flashy, but it was more like one piece flashiness where powers were unique instead of massive destructive projectile one though ten and instakill/instawin techs eleven through fifteen
