The biggest standout in this film is Bondrewd who is just an amazing antagonist. He is loving and compassionate with no genuine ill will to the protagonists but will commit horrible things with no remorse. He wants to discover all the mysteries of the abyss and believes everything he does is completely justified. Even when people don't agree with him, he is genuinely fine with it and doesn't harper any negative feelings towards them. This makes him such an interesting character! His relationship with Nanachi is the main focus of the story and it's definitely very engaging.
Kevin Penkin returns to compose the music for the film and it is still as beautiful as ever. Every song is stunning and elevates every scene. The animation is still great with some pretty thrilling animation in the 3rd act. It also continues to have some really dark moments which is what made the series stand out in the first place.
I have some issues with the film though. Firstly, is the lack of worldbuilding as the movie is completely in one place which is one great aspect from the show that is not in the movie. A new character called Prushka is introduced and ends up being an underwhelming character. She is not very interesting and has limited interactions with the main characters but for some reason the story acts like she was great friends with them. I felt her character didn't amount to much. I'm also annoyed that Riko, the main character, never really does anything worthy of a main character and ends up just being carried by Reg and Nanachi. She doesn't really undergo any proper character development and just ends up feeling like a person who just happens to be there.
Despite all that, this is a great sequel to the first season and I definitely can't wait for season 2!
