Had the opportunity to watch this movie and I felt that this was another Grave of the fire flies (GoFF). GoFF was an animation movie which shows the impact of war through the life of a brother and sister who get separated from their family. Nobody knows shows the plight of 4 children who had to go through hardships when they are abandoned by their mother.
The movie doesn't dwell much on the tear inducing moments rather shows them mostly cheerful throughout the movie but we can feel what they must be going through.
Again watching movies from varied cultures just proves one thing that life is same everywhere, emotions are same everywhere, morals are same everywhere just the languages are different.
