I did love him as my favorite character . . . Until he apologized not for hurting Sakura, but for "everything I have done". Then everything that happens after that moment it is like he abandoned everything he believed in, including Naruto. Then Naruto just "returns this to you" in a way of returning a love letter to someone you are rejecting.
The reason the ending was bad was not because NaruSaku didn't happen. It was bad because everything the main characters worked for and all their development was DROPPED.
Yes! Even if Sasuke genuinely wanted to get with Sakura the real him would've still never apologized for the things he did to avenge his family IMO. He might apologize for being a jerk to her but "for everything he did"? The Sasuke from all 697 chapters before wouldn't have taken back what he did if it was to avenge his brother and family. It's OOC how he completely regretted everything to her in one page.
My point: Even if SS happened Sasuke should've remained prideful and guarded after all the things he experienced. Did he have to go complete OOC?
