Spirited Away is my favorite film of all time. Period. It's a magical movie, each frame beautifully drawn by Hayao Miyazaki. It has some sort of a magical theme to it that just works; it has boatloads of emotion, and has amazing amounts of detail, especially for a hand-drawn anime film.
Most of the characters are just, simply put, strange, from a giant baby to soot-sprites (small, living, balls of soot. With super-strength), something about it all just works.
The plot of Spirited Away is about a 10-year-old girl name Chihiro, who is moving away from her hometown. This feature is actually not as cliché as it sounds, it doesn't have a super-major roll in the film, and it isn't brought up every few minutes like a major problem. She leaves with her parents to their new home. After a while of driving, they tire of the long car trip, and take a walk through a forest. There, Chihiro's parents find an old village, where they feast upon the dumplings, meats, and desserts sitting in the market stands, which turns them into pigs!
Chihiro, now frightened, simply runs as fast as she can away from her now-pig-parents. She runs around the village, lost and confused. Eventually it becomes evening, the whole village then becomes surrounded by water, and she can't escape at all. After a while, she hears muttering, sees lanterns lit, and spirits walk around the village.
Parents should know that If your kid is easily scared, then they shouldn't watch this, there are a few strange parts, a monster eats someone, but it isn't a bloody, grotesque devouring, it's just a swallowing. Kind of like a Muppet eating someone; or something like that. But if they aren't easily scared, then they should easily be able to watch this at around 8-years-old or older. There is also a scene where the No-Face(a monster) pukes, and it's about 5 minutes of screen time. Also, a person has 8 limbs, but it isn't overly creepy.
The movie is amazing; I love it.
