Some of the Who's were downright dark, but flawed in execution. Some of the scenes in the Phil Hinchcliffe (Goth) series were DOWNRIGHT horrific, although the execution was totally flawed. I mean, check Brain of Morbius which had a blinded woman walking down steps and running into a disembodied brain and a collection of spare parts wired together into a body while dodging a psychopath attempting to behead her best friend? The fact that the brain was a joke prop stuck in some glowstick liquid, and Lis "squeaky" Sladen played the woman made it comic, unfortunately... but done correctly eek eek eek nightmare fodder.
