A camera soars above Dublin then glides toward a promontory where a solitary figure stands in front of a memorial plaque. A frothy score wrangles our emotions. Don’t get too sad, it seems to say, before the camera closes in on a sorrowful Lily Fox. Set in 1967, “The Miracle Club,” directed by Thaddeus O’Sullivan, touches on grief and grievances, on unwanted pregnancies and the Catholic Church, while wearing the guise of a redemptive romp. It’s a delicate balance that – even with the impressive triumvirate of Smith, Kathy Bates and Laura Linney – the movie doesn’t always sustain. Lily’s sojourn is one of multiple pilgrimages in the movie. The central journey takes Lily and her two closest friends, plus the estranged daughter of a recently departed third, to Lourdes, France, where miracles are sought by masses of people each year. Agnes O’Casey plays Dolly, the youngest of the trio and the mother of a boy who seems unable to speak. But Dolly is not the only member of the group in need of a miracle.
