While “Heartless” delves into the macabre as Henry (John Noble) unleashes a dangerous “succubus,” or “Incordata – the heartless,” on unsuspecting victims, the underlying message is a variable mix dealing with the faith you should have in those you love and opening your heart to new possibilities, even during inopportune moments. But the succubus (guest star Caroline Ford) isn’t sucking the life force out of her victims to satiate her lustful needs; oh no, she’s on a mission. I wonder if they make baby bottles for demons.
