lemme just say this 'it is a disappointment ' and for the tear jerking part that people keep talking about is nothing but a lie or maybe people are just to much emotional , There was only one scene when my eyes filled with tears thats when he started to cry but that was also for 10 sec only ,and even after finishing it there is no sadness unlike what people keep on saying about this movie. Even a movie like koe no katachi which is not even about death is more emotional than this and for the rest the story was average and predictable and wasnt even very wholesome or heartwarming neither sad nor emotional .
I will rather suggest someone watching movies like Josee the tiger and fish which at least is wholesome at times and also emotional. Even battle shonen animes have made me more emotional but not this other than that. I guess the animation quality was good which is expected for a movie also sounds used were good but not memorable so thats that.
overall experience as i already said was disappointing so i would suggest to watch this movie with your expectations low .
