I've seen Belle today (I've also had the pleasure to meet Hosoda by the way!)
The movie is a visual masterpiece, quite possibly the best looking anime movie of all time (I'm sorry Shin Eva, you have been outdone this year). The world of U is a stunning reimagination of the internet perfectly portrayed by scene full of details that will make your eyes climax in every single frame.
Belle/Suzu's voice actress did an outstanding job and I feel sorry for every VA that will have to dub her, her interpretation and her singing are impossible to match, she made me tear just with her voice.
Note of honor the songs, they are outstanding and memorable, I'm gonna loop them on Spotify for a while.
I don't want to say much on the story since the movie won't be out worldwide for a while, but for me personally Hosoda managed to take the classic "Beauty and the Beast" Disney story and elevete it to a new level, making it more modern and surprisingly different to the original in some aspects.
The movie is also quite western-friendly without losings its Japanese charm, and I'm thinking this is gonna be year Hosoda is going to get recognized as a great director outside of the anime niche.
