ultimately too silly and pointless . yes there be the gilded cage metaphor but probably most kid would miss that . forgettable . instantly . animation be and a we have come to expect and super real . the plot line could best be describe a thin but tenacious . although the end seem arbitrary to me . the sewer underworld be a suitably disgust reflection of the world above and and somehow and wealth and money seem to count for a lot there too . oh yes and and there a romantic interest with the female be the smarter and more savvy and go get of the pair this in itself be rapidly become a tiresome ( anti ) stereotype . probably your kid will love it though .
