Attack of the Crab Monsters

MAY CONTAIN SPOILERS
Was delighted, entertained and moved to floods of tears (of both joy, terror and sadness) by a rare screening of Roger Corman's "Attack of the Crab Monsters" on the Horror Channel today. A beautiful, haunting, fragile piece of filmmaking.
With all the gravity of "Schindler's List" (and more) Corman takes us on a terrifying journey to the darkest corners of the psyche. Marooned on a sinking island, a team of scientists are one-by-one succumbing to grisly death at the hands (claws, as it turns out) of an unseen foe.
When the Crab Monsters finally appear we are confronted with one of the most terrifying villains ever to be forged in the human imagination. The gargantuan crustaceans are everything we can mean by the word 'hideous' made manifest. The terror imparted to our souls by the physical form of the creatures exponentially increases when it is realised that these brutes can speak! "I can grow a new claw," bellows the crab (boasting of its powers of regeneration) "can you grow a new life?!"
It is around this point that Corman, undoubtedly decades ahead of his time, brilliantly departs from trends unquestioningly followed by other 50s movies featuring gargantuan animals and we are told, in a stunning display of originality, that the crabs' size (and speech, it is assumed) is due to the effects of nuclear radiation.
Needless to say, after an epic struggle, the crabs are defeated when the resident nuclear physicist dicovers the crabs can be vapourised by electricity (the scientific foundation of this discovery is explained but went way over my head, I gathered that it is related to how the radiation has altered the crabs at the atomic level but not much more). Mankind is saved.
Exhilerating, powerful cinema. No matter what it takes, I thouroughly recommend everyone look out a copy of 'Crab Monsters as soon as they can.
