"Science fiction film fans will remember when miniaturised doctors were injected into the bloodstream of a human to operate on a brain tumour. Here, you've got to destroy the nerve centre in Zyco's brain. an indestructable (their spelling) alien before your miniaturising pill wears off, avoiding blood corpuscles and antibodies. There is illogicality to this twist on the original. Why does the alien permit injection? And why wouldn't a human body, exploding full-size in his brain, finish him off anyway?" - Home Computing Weekly
