Kimi no Suizou wo Tabetai, also known by the English title "I want to eat your pancreas", is a drama anime film with tragedy. It is about an outgoing girl who has a pancreatic illness which she has not told anyone except her family that she has this illness. A boy from her class stumbles upon her diary that she left in the hospital and she comes back to fetch the diary only to realise that he read it so she ends up telling him about her illness. Due to this secret knowledge of theirs that none of their classmates know about, they start to grow closer. Sakura Yamauchi, the girl with the pancreatic illness, notices that the boy is a bookworm and does not talk with anyone and does not have any friends so she feels she has some sort of duty to become friends with him and change him for the better. This all sounds good on paper, but it falls short due to the way this film was structured along with other things that this review will touch on. Some scenes felt out of place and did not add much too the film's main story.

The animation of this film was quite disappointing. It seems that this anime film didn't have much of a budget and a lot of the animation was quite lazy. This film was very much heavy in dialogue to make up for the still shots of animation that had a pan effect on the cinematography showing several still animated shots in one after another that conveyed the character's activities rather than animating their movements. This made the movie tell the story verbally rather than showing it to us and it felt very lazy. Due to this sequence of several still shots throughout the film, it felt very rushed in terms of pacing as it was evident they were trying to squeeze as much as they could into this film.

The soundtrack was not memorable and the opening theme was just shoved into the film in a distracting and "pushy" way. The voice actors did a good job though. No real complaints in that department.

Character development was okay. It could have been a lot better. I liked how they symbolised the unwillingness of opening up doors for friendship with the rejection of taking gum when offered by a classmate. I thought that added a nice little metaphorical touch to the anime film. Where this film lacks though is the reasoning with the actions of the cast in this film. I could not get fully emotionally invested in the relationship between the two main characters as their attitudes and emotions seemed to have a convenient "light switch" wherever it was convenient for the plot to do so. Yamauchi's best friend was a character in this film which was included just to add unnecessary drama to this anime film which could have been a bittersweet tale with more character development on the main characters' relationship but it decided to be more of a rivalry with attention and dictatorship of who Yamauchi should be friends with or the reasons as to why the other characters do not open up to the introverted boy.

I still found some enjoyment watching it as there were sweet moments that occurred in this anime film. It's just a shame that it was tainted by the poorly written aspects of this anime film.

I found this anime to be similar to another anime called Your Lie in April, particularly with the motivations, actions and relationships that are conveyed in both anime. I would suggest watching Your Lie in April instead of this if you have the patience of watching an anime series rather than a film. I cannot recommend this anime unless you find deep enjoyment watching growing friendships within characters that is interlaced with tragedy.

If you do end up watching this anime film, stay to the end of the film as there is a post-credit scene which does make the film a little bit better and adds a better conclusion to the ending before the credits roll.
