“To summarize the plot of Mandy would probably take about two sentences and be entirely beside the point. This is an atmosphere picture steeped in dread, punctuated by heavy metal blasts of cathartic carnage. The movie isn’t just set in 1983, it feels like a memory of something you might have watched that year on late night cable after your parents fell asleep.” – WBUR’s The ARTery, 09/11/2018
