Grabbers

An idyllic remote Irish fishing village - replete with twinkly-eyed eccentric Waking Ned Devine characters - is invaded by enormous tentacled creatures from the sea who are picking off the villagers one at a time. The inhabitants learn that the one thing the creatures don't like is alcohol, it makes people taste horrible, so they realize that in order to stay alive, they're going to have to get as drunk as possible.
