As everyone else said, I think the actress who played Hachi didn't fit her. The Hachi from the first movie played her excellently. I will say that the Shin in this movie was a better cast.

I don't think I noticed this in the first movie, but for this one, wow! The wardrobe and accessories were very accurate; I think they did an amazing job. This is such a great adaptation; the script, cinematography, and clothing are spot on and it was satisfying to see. It felt rewarding to watch this after finishing the anime, I enjoyed it.

Overall, it is an excellent adaptation and movie; well done. I'll love the story of Hachi and Nana forever.
