Watching a video on Kreia from Star Wars Knights of the Old Republic II. Here's a quote from her that summarizes why NaruHina happening because of Kishi's pity feels so wrong.
It's also why giving Naruto a bunch of powerups at the end, as well as explaining the advantages he had at the beginning due to Uzumaki blood, only served to undermine Naruto himself so greatly. He was supposed to be the dead last, the loser who failed the genin test three times. It's why him learning the Kage Bushin technique resonates so greatly, as he overcame his own defeats and came out stronger than if he had simply passed. Remember, having Kurama was originally a double-edged sword as it affected his ability to control chakra as well as the damage it did to him when in tailed-modes. Naruto being able to contain the 9-Tails became cheapened when it was revealed that he was only able to do so due to his heritage, along with other beneficial Uzumaki traits. Naruto learning to work with Kurama felt great and like the Kage Bushin it meant something. The god-mode powers Naruto was given at the end of the series lacked this, and like Kaguya felt out of place to the rest of the story.
But back to NaruHina. With Hinata being given her husbando, it ultimately denied her the character growth she so desperately needed. She remained the same little girl she always was, chasing after Naruto even when she swore she wouldn't anymore. Her lack of focus ultimately hurt her, as it removed the struggle from her pursuit. Naruto just ended up with her at the end of the manga despite everything that pointed to him shacking up with Sakura. Then The Last came along, which served to invalidate Naruto's feelings for Sakura to remove her as a threat, all while trying to establish Hinata had already won years before without knowing.
And if we go off my previous analysis that Hinata believes she has to defend Naruto from everything, their relationship only seeks to weaken him. It's not Hinata who is getting Boruto to understand his father's (supposed) greatness, it's the experiences Boruto has outside of their family that will ultimately mature the little poop and restore his relationship with his father. Again, Hinata's problem is being solved by someone else saving her the trouble and means to grow, likewise it's solving the problem for Naruto to continue validating the behavior that created the problem in the first place.
It denied both Sakura and Hinata and Ino character growth.
Hinata moving away from Naruto.
Sakura and Ino moving away from Sasuke.
I bring up Ino because let's be real. She only got with Sai because he was Sasuke's replacement.
