In the short documentary 'Nǎi Nai & Wài Pó', filmmaker Sean Wang provides an insight into the everyday lives of his two grandmothers, both of whom live together in their old age. There is no real narrative, which makes it a little difficult for me to rate the film. Although both are interesting characters, there isn't much going on in the film. There isn't really a clear message, except perhaps that you can still have fun at an advanced age. All in all, it's a cute little movie, but nothing special.
