Great acting, chemistry, & interplay between leads David (Mike Colter), Kristen (Katja Herbers), & Ben (Aasif Mandvi)! Each sees good & evil through a different lens: David-religious, Kristen-psychological, & Ben-hard science. They all partake in a balanced way in solving ingeniously conceived mysteries. Great supporting cast especially Kristen's four believable & adorable "children", Kristen's smart & "hard-living" mother Sheryl (Christine Lahti) & the brilliant psychopathic/demonic Dr. Leland Townsend (Michael Emerson). Intelligent examination of "good" v "evil" (great & small, secular & spiritual), human v supernatural agents, & how human weakness & psychosis, technology innovation, & institutional power are leveraged by these agents. Highly recommend this series!
