Sheng si xian (1985)

John Shum leads an expedition to an supposedly deserted island only to find out that it's inhabited by a group of seriously demented characters,lead by Peter Chan Lung.This is a family that stays together,slays together and when the youngest one is refused in marriage to one of the young girls of the troupe they turn into savage maniacs.Obviously inspired by Tobe Hooper's "The Texas Chainsaw Massacre","The Island" offers very few nasty surprises.The villains are quite outrageous,but the gore and violence is kept to minimum.In fact the majority of the film resembles cheerful HK comedy loaded with silly humour and it's not until the hour mark that the horror truly begins.Hong Kong filmmakers often seems very desperate to include laughs whenever they can and "The Island" is no exception.Check out "Flesh and the Bloody Terror" or "Corpse Mania",if you want truly grim early 80's HK horror.
