I see people are already freaking out about the Naruto thing, so let me calm you down.
1. Destin Daniel Cretton is a GREAT director. The movie is in good hands.
2. Sasuke's crush on Sakura is subtle. He's still all about revenge. Sakura's crush on him is also subtle; she's not crazy in love with him like she was originally.
3. The Jinchuriki thing is kind of in the manga too. Yes, technically anyone can be a Jinchuriki in the manga, but it still mostly goes through generations. So here, they just streamlined it and also did it to make it make more sense why his parents had no choice but to seal the Fox inside him.
4. The changes to Sakura are meant to make her stronger and more prominent. If she didn't have her post-Tsunade powers, she'd be useless. Her father being dead gives her a backstory, and her conflict with her mother gives her a home life that she didn't have in the original.
5. Naruto is a history nerd, but he's still not good at school. He's not a genius nerd.
6. It IS faithful, with a lot of scenes recreated almost shot-for-shot from the first arc of the manga. The changes are mostly character-related, and they don't affect the story as much as you might think.
