Low-key and ruefully well-observed, France’s “Let It Rain” is nevertheless too slight to make much impact. The writer-director Agnes Jaoui stars as a feminist writer turned politician who returns to her hometown in the south of France to visit her harried sister and do interviews with a pair of bumbling documentary filmmakers (Jaoui’s longtime partner Jean-Pierre Bacri and Jamel Debbouze) who are making a movie about successful women.
Revelations, romantic and otherwise, ensue in a light, reflective but only mildly engaging dramedy that comes as a disappointment after Jaoui’s more pointed previous films “Look at Me” and “The Taste of Others.”
