The director of “The Girl from Paris” and “Joyeux Noel,” Christian Carion sets up a story of a strange kidnapping for “My Son.” A French production, nothing is immediately clear in the tale (scripted by Carion and Laure Irrmann), which blends the terror of sudden loss and the weight of guilt with those forced to deal with such a horrific invasion. While the nightmare seems to lean toward the bitterness of domestic resentment, Carion has something more visceral in mind, keeping away from a somber Euro analysis of pain to become a thriller of sorts, gifting star Guillaume Canet is own chance to perform in a “Taken”-lite actioner. “My Son” is tense and twisty, and it doesn’t mess around with melodrama, with Carion most interested in feral responses to an unthinkable situation.
