“Silent Night, Deadly Night” (*1/2 out of four) was a needless remake of the 1984 unwatchable mess that is somehow now regarded as a cult classic; once again a troubled young man (Rohan Campbell) witnesses his parents getting murdered by a killer in a Santa Claus outfit and it scars him for life and makes him grow up to be a psychopath on the loose. Incredibly- this is actually the second (!) remake after 2012’s far more stylish “Silent Night.” Loaded with terrible dialogue and unbearable attempts at black humor and irony.
