I've watched the anime and am on track with manga so I came into this whole ordeal with high expectations.

1. Story - it deviates from the source, and for the worse. There are so many other characters in the manga that could've made the entire movie so much more interesting and far funnier than it turned out to be. I understand it's an adaptation, but it's still a downgrade. For the most part, it felt so rushed and forced to tell a complex story in under 2 hours.

2. Cast - The actors themselves were okay, Fujiwara was by far the closest to the manga one. However, due to the story rush, characters and their personality traits suffered a lot and Ishigami and Fujiwara appeared mostly as token characters - there because they have to be, not because it feels natural. We find out nearly 0 things about them.

3. Music - I wish they used the openings from the anime since they're unbelievably good and set the perfect mood for the story. Music in this movie didn't make much of an impression.

4. Rewatch value - overall meh.

I feel like making Kaguya sama into a drama would've been far better as the story would have time to naturally progress and we'd get to know characters more. It really is an amazing manga - so much so that even anime adaptation seemed rushed so this is by far the most underwhelming option to watch.
