To me I seriously think the anime captured the moment correctly, save for the blush Naruto lacked (his eyes definitely made up for it though). She WAS about to cry, because Naruto is so dense and just OUTRIGHT REJECTED her in front of everyone. She had many intentions in this confession and I think she didn't expect Naruto to be so cold towards her(whether she was about to cry or not, she had the pained expression of a girl who was just rejected, I feel so bad for her and Naruto, their love is so complicated, so much for them to get through before they can finally love eachother). Seeing the anime version of this gives me somewhat new perspectives.
Naruto is too dense to see that she's changing and that he actually has a shot at the "unattainable fangirl of the Uchiha".
Sakura wasn't able to see that Naruto WANTS to, with his own will, save Sasuke. She thinks it was MOSTLY out of Naruto's love for her that he would keep trying and trying, endangering himself in order to save Sasuke. However, she finally gets it that Naruto does it because HE wants to. His persistent attitude fails him to give up... But Sakura doesn't want Naruto to be endangered anymore. She said herself "Worry about yourself for once!" She sees that he's so selfess as to always put others first and forgets himself sometimes. I think Sakura is doing well in the aspect of opening Naruto's eyes to the fact that people want him in this world and it would kill others if he died. That's why he was so shocked to see Sakura worrying about Naruto and how he always chased after Sasuke. She wants Naruto to come back to Konoha with her where they can be safe together. But Naruto, being his stubborn self, refused to believe it, refused to give up on Sasuke. I really cannot say what Kishimoto has planned for team 7 anymore... in the love triangle aspect. It's just been way too confusing... Naruto loves Sakura and Sasuke... Sakura loves Naruto and Sasuke... Sasuke doesn't love anyone but after seeing how much they have cared for him he will eventually right...? Personally, and many others have said so too, that it's too late for Sasuke to have a shot at romantic love, he has too much redemption to make up for. Sigh, idk if Kishimoto is trying to use this chapter as a scene of Sakura's changing feelings and how Naruto is starting to learn and grow up, seeing the different feelings one can have over time. I just don't like that Sakura keeps lieing about how she doesn't about Sasuke anymore. That's so not true.
But yeah the task of getting Naruto safe is in her hand, so she's willing to lie... And her blush in those scenes really spell out that she is TRUELY in love with Naruto. I wish Kakashi finished what he was saying, that wouldve been GREAT insight. However, Naruto DOES know Sakura very well... I have no idea if he's RIGHT this time about her lieing to herself though... This confession can be altered and interpreted in so many darn ways >.< I'm seriously losing it haha. So exasperated.
Edit*
Perhaps, hopefully... Naruto saw how Sakura said "I don't care about Sasuke anymore... *fake smile*" Perhaps this is what brought on Naruto's suspicion. It's not that he believes Sakura is lieing to herself about her feelings, but about how she's lieing that she doesn't care for Sasuke anymore. Naruto just doesn't see why she's lieing about it, but we as the reader do. Sakura has that task of telling Naruto about the disposal of Sasuke and has decided to HIDE it, this brings on Naruto's doubts and suspicions of everything, that's why he ends up not fully believing her. But perhaps it was 100% true despite all the hidden things concerning Sasuke?
You actually nailed it on this point. The anime captured Sakura's confession beautifully (and even backed it up that she truly loves Naruto with flashbacks of her actions in the Pain Arc: from calling out for him after Pain Shinra-Tensei'ed the village to her hugging him when he came home). Even her outburst after Naruto said that "she's lying" was realistic. I didn't even expected Sakura to slapped Naruto's left hand off of her when she was making her statement! I was like, "Whoa!!! I didn't see that coming!" Though I lol'ed when she slammed on Kiba's foot. Kiba's ouch expression = priceless!

At first, while looking at Naruto, they did forget the blush (and the redness on the nose since he was outside in cold and snow, without a damn coat on!) and it was very awkward and making it look like Naruto is the bad guy as Alexander said... however, by reinterpret the scenes, like you said Yoshimoya, it was the looks of his eyes that was spot on.
But yeah, this is
drama for you! This was definitely one of the scenes that Kishimoto decided to escalate
not the romance but the drama of the story which made every single fan crazy on a pickle when we first read the chapters on the manga. This is part of the scale when Naruto began to realized that everyone does changed, including Team 7 and have to stop living in the past where Sakura was still the ultimate Sasuke fangirl and Sasuke was... well, Mr. "so-called" goodie-two shoes. Time to move on and get out of that fairy tale.
As for the opening, it was alright. I didn't expected any NaruSaku or any SasuSaku because that's not what the openings are about. They only show what is currently happening in the storyline in an artistic/fantasy setting. The way I see is, which we will see later in a couple of episodes later, that Sakura now truly sees Sasuke a truly different, yet very cruel person. You can see at the end of the opening that Sakura brought out her kunai which signifies that she is going to kill him (which will be unsuccessful).
