Graveyard of the Fireflies.
What is it about?
The saddest movie ever made. I felt really sad for the girl, but anger towards the boy for continually making wrong decision after wrong decision even when told he should do something different by the adults around him.
That was the best movie I will never watch again...
"Fireflies" is not intended for small children by any means. It's suitable for pre- and young teens with some parental guidance--kids need to know the historical context.
Teraithia is a pre-to-young teens book. I didn't care for the book at all, frankly, nor did my daughter. But when we saw the trailer for the film we both remarked that it seemed not at all like we remembered the book. The filmmakers have added lots of fantasy stuff that wasn't really in the book at all.
