I saw the film in Taiwan, with Chinese subtitles. Disclaimer: I am a non-native speaker of Chinese, so often times I couldn't read the subtitles fast enough. However, I still understood most of the film, and tbh you don't need to understand the dialogue to get the gist.

The story is a bit cliche, with the main conflict dealing with Adachi's work transfer. I felt it was pretty slow at times, and the pacing was a bit weird.

There are definitely enough sweet moments, but not enough of the second couple, imo. Also, I can't believe I'm saying this, but I would have liked to see more of the girl (and Rokkaku). There were also some touching moments which made me almost tear up.

The music and acting were fine, but I didn't really pay close attention to them.

Overall, if you are a fan of the series, you can't really not watch it, but if you haven't seen the series, I think I would pass on it. My friend who I watched it with hadn't seen the series, and said he enjoyed it, but mostly because of the attractiveness of the main leads XP

Anyways, I hope you got a general idea of what to expect from the film.
