I suppose we have to remember that we're in the minority in the west. Other than this website, it seems like everyone on the internet hates Sakura more than anything in the world and they support Hinata simply because she's not Sakura.
Maybe I looked too closely at the characters and lost the ability to relate with the average fan. Maybe the real mass appeal was ninjas and fighting, and anything that impeded that got looked at with scorn. Sakura was often put in positions where she was either a liability in the fight or far outclassed by the other fighters. If you combine that with her bratty fangirl attitude at the start you can see why more casual viewers would hate her.
And then I have to ask myself, did anyone consider the ending to be good? If 100 random fans read the final chapter, how many would have thought it was a good end to the series? Would that number have been higher or lower if we got a NaruSaku end?
Honestly I think it would have been lower. Even if it was better writing, even if it was truer to the characters, even if it led to a better sequel series, it still would have been utterly rejected by the masses. Ultimately Naruto is just a product, and Jump is a business.
I would just really like to know Kishimoto's thoughts on what happened. It's frustrating even years later not having answers to all these questions and Naruto's continued relevance even if diminished serves only to remind me of the way Jump butchered a decade long story so they could keep it going just a little bit longer.
