The Texas Chain Saw Massacre (1974)
From the very first seconds of The Texas Chain Saw Massacre, which expose the audience to flashed images of decomposing flesh, to the subsequent news report detailing grave-robbing in rural Texas, followed by the oozing red sunspots of the title sequence, and the opening narrative shot of armadillo roadkill, the viewer is transported to a nightmare zone where usual moral parameters are null and void.
