There are many glowing reviews of this movie, but mine is not. Although there is some dialogue in this movie, the experience would hardly be altered if the sound track were muted. And, in fact, segments of the dialogue are so low-pitched that one cannot make out what is said at all. No loss!
Basically we have here a mother who is looking for a companion that will make her feel she is living an adequate life. She is housing and feeding her daughter and herself and a revolving door of successive possible saviors, but she isn't finding personal salvation. Only initial ones that somehow are unsatisfactory after a brief trial.
Rave reviews underplay the monotony of the movie and its absence of progress toward satisfaction. She cohabits with believers in Buddha, in mysterious nature, in big bang but, frankly, neither herself nor her chosen teachers of a "way" exhibit any understanding.
We end up with the daughter having reached exactly these conclusions, along with the audience, so at least we part on the same page.
The movie invites the viewer to look for symbolism, an allegory. The mother's search is perhaps that of humanity, and her "saviors" perhaps the abortive philosophical attempts of mankind. The daughter is the hope that a new generation will be more successful. And, perhaps, the final square dance is the admission that, like a dance, life's meaning is that it can be enjoyable for the moment, even though it will end and will be forgotten.
My title for this review and my summary: not illuminating.
