“Curious” (** out of four) was a lurid melodrama about a husband-and-wife (Anthony Applewhite and Terri Arcelia) who meet a new woman (Lindsay Diann) and they all enter into a dangerous sexual triangle together that challenges all of their sense of sexual security and sanctuary and eventually leads them all into danger. In 2011- David Cronenberg told virtually this same story far more skillfully and vividly in “A Dangerous Method”; film is attractively shot and made but carries little in the way of traction or lasting charge.
