I feel ashamed of knowing the movie has released in my country after a week. Anyways, the movie is good, even though I feel that some of the stories are unfinished. Nevertheless, I still cannot memorise all of the information in the movie. So...sorry of the limited information I can tell.
The Musashino Animation is not closed, but almost. It was because of the tragic incident about the other company takes their character designs back, which reminds me of the incident of Kemono Friends in real life. I really want to watch the TimeHippo incident(An animal title too lol), but alas, only some mentions in the movie.
