Adapted from her own stage play, Emma Dante's film 'The Malacuso Sisters' serves up a trio of vignettes of a Sicilian family at different stages of their lives. Key to the story, such as it is, is a tragedy that strikes them at the end of the first part. This beginning, in which the sisters are still children, is nicely assembled and deftly observed. But thereafter the film fails to develop (rather than just imply) a plot, and relies on heavy use of sentimental music to paper over the cracks. One feels there's a tale to be told about these people; but somehow this movie shies short of telling it.
