A cautionary tale about the prolonged effects of LSD, that become a thrilling horror film. The exaggeration of the possible side effects of hallucinatory drug use in collage does a great job of building suspense, and gives seeming normal people motive to kill their closest friends and relatives. My only concern is that by using LSD as a catalyst for the mental collapse which leads to murder, it brings only more resentment for the "acid culture" that's already mostly misunderstood.
