Also known under the alternate titles They Came From Within and The Parasite Murders, Shivers is an ingeniously engineered slash of thoroughly modern horror that, like George Romero’s Night of the Living Dead, charts a social breakdown by tearing through our most intrinsic taboos.
Though "Shivers" occasionally echoes a couple of its forerunners, "The Tingler" (1959) and "Night of the Living Dead" (1968), the film achieves its own peculiar power with one ingeniously lurid scene after another.
Like The Texas Chain Saw Massacre (Tobe Hooper, 1974) and Night of the Living Dead (George A. Romero, 1968) this had the effect of making a more visually disturbing film.
