Mother of God, is Gloria (Lola Duenas) one of the craziest characters to hit screens in years. Major applause to Duenas, who encapsulates pure insanity as a quiet woman who reluctantly goes on an outing with online dating guy Michel (Laurent Lucas). The two have a one-night stand. Gloria, who isn’t all that quiet after all, wants more, even after finding out she is just one of many for Michel, who fancies himself a regular Don Juan taking advantage of lonely women for their money. Gloria wants in, and she poses as his sister in his schemes. She has a little jealousy problem, however, and starts murdering the women Michel is attempting to defraud. Director Fabrice Du Weiz makes the movie an often uncomfortable one (not a complaint), and dots the movie with the occasional “so bizarre” moments, such as when Gloria breaks into a heartfelt song before sawing a victim’s leg off. The movie is “loosely based” on the Lonely Hearts Killers, who killed women under similar circumstances in the late ‘40s here in the good old U-S-of-A. Duenas and Lucas give us one of the more diabolical screen pairs since Beatty and Dunaway in Bonnie and Clyde. Actually, they make those infamous robbers look like missionaries.
