“The Mother” (** out of four) was a misbegotten action melodrama about a retired C.I.A. assassin (Jennifer Lopez) who comes out of retirement and hiding when she finds that her daughter (Lucy Paez) is being threatened and she has to defeat various long-lost villains to protect both of their lives. Well-made and well-acted movie is also hollow and overlong; Lopez is rock-solid as always but this story worked better decades ago with Matt Damon and the “Bourne” series. Ben Seresin’s exquisite cinematography is a definite asset throughout.
