It's not an exaggerated statement, because this movie has proven the statement above.
Almost cried when I watched this movie, my eyes were glistening.
Chan's life wasn't easy. He lost his little sister and her mother treated him like someone else. But the ending part of the movie attracted me and successfully made some of my friends dropped their tears. The dog's sacrifice, that was the main point of this movie. Faithfully stayed together with his owner, until the last time of him.
