I love this movie so much, I've watched it so many times and it's by far my favourite movie ever. It is extremly heart warming, sad, and nostaligic.
It is the only movie that has ever made me cry, which proves the sentimental value within the flim.
I've loved Doraemon since I was 4 and when this movie released it made me so happy.
Anyway, If you haven't watched it yet, I'd recommend you do so.
