Yes and no. I like the concept of what Kishi tried to do, I just hate how it was executed such as how poor of a job Kishi did on explaining Kaguya's purpose(s), concepts of chakra, ashura and indra, and overall history of the planet. I mean why did Kaguya come to Earth? What was Kaguya's reasoning for a zetsu army? Was Kaguya royalty or some form of princess for her people? Some small details, but still unclear.
As for Indra and Ashura, it was really unclear but the concept came from Hinduism if I'm not mistaken. Either way Kishi tried too hard to make them equal and tie into the story, and ultimately painted Ashura as a weakling in the process, such that he was initially weaker than his brother Indra, but gained equal power, later he received some other power from Hagoromo but he ended up dying in combat to Indra, despite being a power up over him? I could assume Indra received some other power up not from Hagoromo but the manga doesn't even say that, so either they were not equal beforehand or Indra got another power up or something else. But I digress. In my opinion it would've been better just to have them equal in the beginning instead of trying to force Ashura to represent Naruto as the "untalented one", just to make Naruto relented to the plot/back-story. Although Naruto's relevance to the story is another issue.
Hagoromo and Hamura ultimately could have been ignored, heck Hamura was ignored for nearly the entire manga, with like 3 or 4 feats/images in the story. Chakra could have been handled like other stories handled power, just some ability everyone has or it's something people gain through training or whatever. Kishi tried to explain how chakra came but it lead to some issues, especially with IT effecting people who lack chakra, despite genjutsu effecting chakra in the brain, so I guess IT becomes another exception to the rule. Hagoromo and Hamura could've just been people who sealed the juubi, but didn't really interact with the plot as much.
Then there is the issue of how the moon was created and it's overall place in the timeline. (Not sure if Obito's words, of Hagoromo making the moon on his deathbed, were retconned or not.) Either way if that was the only moon, how was there waves in oceans prior to its formation? How was there tide? Not sure if this was answered, but this feature could actually be removed. Heck the Juubi could have been sealed underground in volcano. Then again maybe it was two moons in the beginning, IT happened with Kaguya so she must have had to reflect it on the moon....
Ultimately I figure Kishi had good intentions but his lazy writing or just fudging the issue, lead to unclear concepts that he tried to introduce and at that point, I would rather he not even introduced the concepts in the beginning.
