Surprising similarities between Bowen's novel and the contemporary movie Roma

Oddly - although echoes like this seem to happen more than I'd expect - the book I'm reading - Elizabeth Bowen's 1938 novel The Death of the Heart - makes a companion piece or counterpart to the movie I saw last night, Roma (Alfonso Cuaron). In Bowen's novel, as noted in previous posts, a well-to-do young London couple take in the husband's 16-year-old half-sister, recently orphaned, but greet her and treat her with such coldness and suspicion that she feels unwanted and alienated, though she finds some solace in long conversations w/ the family servant and with a 23-year-old guy, friend of the family, who begins to date her but seems to have huge problems forming and sustaining relationships. In Roma, a well-to-do couple in Mexico City, with 4 young children, begin to come apart at the seams as the father walks out on the family and the mother, frustrated and angry, takes her anger out on the servant; the servant, meanwhile, seems to be the only one w/ whom the children have a positive and loving relationship. So the "structure" of these two works and the social milieu of each seem to me strikingly similar - though in Bowen's the focus is on the teenage daughter (Portia) while Roma focuses on the household servant (Cleo). In Roma, unlike the Bowen novel, the servant undergoes huge trauma of her own; the family helps her, at least a little, but the adults are largely oblivious to her presence - she's of a lower social class and hence disposable. In the Bowen novel, the servant - Matchett? - is hard-working and proud of her position in the family and, so far as we see, has no social, intellectual, or family life of her own. Roma is by far the more emotional and caring of the 2 similar works; the further I read in Bowen's Death of the Heart the more I'm struck by the coldness and reserve of the couple (Thomas and Anna) and their inability to provide a loving home for Thomas's young half-sister.
