“The Carters” (*1/2 out of four) was a pointless horror thriller set in the midst of the COVID pandemic in which the title family (QuanNae Coleman, Ciara Cravens, Cameron Cottrell, and others) struggle with the aftereffects of the virus and also the vaccination and how it turns all of them against one another in the facility that they all confer in. Part horror thriller, part social and medical commentary, part family comedy and pretty much an all-around mess. Film doesn’t so much end as stop, assuming you make it that far.
