“It’s astonishing how little interest the movie has in exploring its provocative premise, with none of Rock’s incisive political sensibility to be found in a film that’s all but begging for it. With subtext-as-text horror like Get Out and The Purge pictures being all the rage these days, Spiral feels sheepish and timid, gory in a way that’s afraid to draw any real blood.” – North Shore Movies, 05/17/2021
