They should have left that egg and other stupid stuff aside, It would have been a much better plot.The only good thing about the entire movie was the ending, because of the song.
This story had a meaningful premise with a girl who comes to think her words are nothing but poison to those around her. So she decides to never speak again to save herself from destroying anymore of the lives around her. I found myself trying to compare this movie to A Silent Voice, but this movie had far more glaring issues.
The largest culprit was the egg. When mixing self fantasy into a reality, it really only works when that object or dream has a strong metaphorical value or connection to the character. In this situation, the egg just felt like the writer chose some random object, and arranged the story with it. If there is a cultural significance to the egg in Japan (as the symbol of creation/birth perhaps), it should have been better explained.
The animation and voice actors were nice, not breathtaking, but quality. The music was excellent throughout and I loved the way the movie used it to express the major plot points throughout the film. Side note: I would be careful where you watch this one, since there is a very poor quality English sub out there (misspellings, poor formatting, missing lines, etc).
Overall the movie was decent. I think it certainly could have been made better.
I GIVE THIS A 1/10 , SIZZIE PAPAASAHINN LANG KAYO NETO
