Transmigration in a way considering it diminished one of Naruto's qualities such as being the underdog who rises above the genius.
I would've enjoyed it more if Ashura did lose to Indra, thus, Indra was the successor who triggered the chain of hatred while Naruto steps up and eventually has to fight Sasuke, Indra's Transmigrant and proves that he can still alter his destiny and beat Sasuke despite what happened to Ashura. Of course, this would cause some of the story to be revised such as Hashirama beating Madara, but at least it wouldn't contradict what was established in Part 1.
