The plot about Tonerie wanting to restore his clan is okay, him taking Naruto and Sasuke's powers makes sense considering he is a decedent of the otsuki clan. This is a plot that's never really been touched upon which is kind of exciting! Those saying he's a "male version of Kaguya" aren't completely correct in that statement.
I think the part that actually makes me kind of upset is Naruto's character. I can't believe after everything that happened in the war with him and Hinata not to mention him bearing witness to Sakura's confession to Sasuke, that he still likes Sakura! I'm sorry, but it really just ruins the integrity of his character for me. He clearly has a connection with Hinata, he saw it, she saw it. It was hinted on a lot throughout the war, it's so disappointing that Kishi contradicts nearly two years of building up Naruto and Hinata's emotional connection in the first 30 minutes of his new movie.
I'm not saying I don't like the concept of the new movie, I really like the plot, I love Kishi's work, but he's really bad at developing mutual emotional connection between male/female characters in this instance anyways. It makes Naruto look dense as hell and frankly for a character that is able to reach so many people around him emotionally, he lacks common sense. It's a little frustrating.
