TBH.... I started Naruto after Tobi's identity was revealed.... So.... And I think MinaKushi is more like NaruHina cause Minato and Hinata are calm headed and Naruto and Kushina are hot headed.... One is a chilled out and the other is bad tempered in both pairings.... And Sakura gaining seal was a little obvious I think....
Ummm....what? While I understand your opinion is your opinion, but...how is Naruto "hot headed" like his mother? I don't recall Naruto ever getting "hot-headed" or "bad-tempered" at anyone. Sure, Naruto is as tenacious as his mother, but hot-headed? I am not sure where you get this idea from.
And since well, chapter 631 especially said that Sakura is just like Kushina...I don't think MinaKush = NaruHina is even real fact, but rather fan wishful thinking.
Sorry, but what Kishi says goes and he makes the parallel to Kushina and Sakura...and at many of times compared Minato and Naruto.
You're points are valid, however, Sakura will never, ever love Naruto.
She has no perspective on romance and love interest. She is locked on Sasuke and will never look towards anybody else.
Then I guess no pairing will be canon because Naruto doesn't see Hinata as his love interest and, according to you, Sakura doesn't see Naruto.
Everybody loses.
The problem is that NaruSakus do exactly the same mistake that NaruHinas do. In the same way NaruHinas dismiss Naruto feelings, NaruSakus dismiss Sakura's feelings. You guys put faith in the scenario that Sakura will turn around and go for Naruto in the same way that NaruHinas put faith in the scenario of Naruto turning around and going for Hinata.
Another thing is that personality wise, Naruto isn't like Minato and that idealistic wise, Sakura isn't like Kushina.
Unlike NH fans however, we actually have moments of Sakura showing interest in Naruto. So it is not just "faith" alone that makes us believe. Would you have thought Naru and Keitaro would have gotten together out of all the times Naru rejected, punched, and denied her feelings for Keitaro?
SS fans also have this problem in thinking Sasuke will turn to Sakura, but like you said has shown no hint of him reciprocating anything. I think that's the point, Sakura was the only one to have hinted to change meanwhile Sasuke and Naruto have remained the same through out the series.
As for the parallels, Hinata has no connecting traits with either Kushina or Minato. I don't know why everything thinks she does, but Kishi has said that Kushina and Sakura are parallel. Whether you agree or not is not up for debate anymore. If Kishi, the creator of the manga, says "Yes, they are parallel" then you have to accept it.
I'm sorry, but people need to read the manga itself and not just read what they want to read.
