Story: Jo Grant, the Doctor's assistant, decides to help a group of environmentalists in their protests against Global Chemicals who are attempting to use a new, more productive technique to refine oil in an old Welsh mining town. This presents a conflict of interests when her boss, Brigadier Lethbridge-Stewart, anounces that he has been tasked in protecting Global from the eco-terrorists by providing security. The doctor gets involved when an miner, sent to perform rountine checks on the abandon mine, collapses and dies while he skin turns bright green. Global Chemicals are unsurprisingly revealed to be the villans and have been dumping their highly toxic waste into the abandoned mine to save costs. The waste has mutated maggots into glowing green killers which have to be stopped before they turn into flies and infect the world! If this isn't enough, Global is actually run by a meglomanic computer with the ability to control minds of humans and is intent on taking over the world. Can the Doctor stop the mad computer? Can the Doctor find a cure for the infected Jo Grant? Can the Doctor kill the maggots and save the Earth? What do you think!!!???
Feeling like a cross between a Quatermass film and the old William Hartnel episode "The War Machines", The Green Death is an enjoyable romp from the Pertwee "exile" period. The wriggling green maggots are (fondly?) remembered by all children who watched the original transmission back in the '70's, the cast ham it up beautifully and the story ends on a sad note as Jo elects to leave the Doctor for a young scientist. While the scipt is very good and moves along at a decent pace, the effects are unfortunatly typical for the time period - the CSO (green-screen) effects in the mine are awful and the flying insect is laughable, however the maggot infested slag-heaps and the attacking maggots are done very well.
