This is the original 6-part teleseries that was the follow-up to the earlier teleseries, The Quatermass Experiment (1953). There is something very wrong with a huge chemical factory out in the wilds of rural England. An alien horror is afoot! The scenes in this marvelous teleseries range from thought-provoking to downright terrifying. Wow... A terrific script, is complimented by great, believable performances. British science fiction doesn't get much better than this.
