Loved it. Awesome family film.
The film's about a young boy, orphaned after his parents died while mountaineering, who is sent to live with his uncle and attend the school he runs in a remote village.
But it turns out that the teachers are cruel and abusive, and the uncle steals from the school's funds for his own financial gain. When it looks like he could lose everything, the uncle fakes the boy's death (he leaves him at an amusement park in the city) and claims the boys incredible inheritance.
The boy finds his way back and with the help of a spirited homeless woman and a mysterious man living in a bungalow that's considered "haunted" by the superstitious villagers, the boy becomes a hero known as Zokkomon.
I totally recommend this for your next family movie night, though only if you and your kids don't mind subtitles, since the movie does not feature an alternate English dub (unlike, say, the films of Studio Ghibli).
