Bone-Sucking Beasties ARE Creepy!
6 June 2003 | by (USA) – See all my reviews

I saw this film for the first time several years ago on a Saturday night broadcast on The Sci-Fi Channel and I was an immediate fan. How can classic sci-fi and horror fans not enjoy this film? It has a neat story, some gruesome sound effects, a top-notch cast and a great director. The film takes place on an island off the Irish coast and that's an immediate bonus....films where the population is trapped on a ship, island or in a house always add to the dread of any film, in my opinion. It makes for a smaller cast and you get to know the characters a bit better....this is definitely the case with this film. A medical research team it seems has been experimenting and attempting to find a cure for cancer, certainly a noble effort, but instead, they develop a new breed of creatures that live on the bone of humans and animals. Once a local is found void of any bones, enter Peter Cushing as Dr Brian Stanley and Edward Judd as Dr David West. West's girlfriend, Toni Merril (Carole Cray) also accompanies the Drs to the island and this is where the film really takes off. Bodies begin to pile up, the gruesome sounds of the 'beasties' liquefying/sucking the bones from their victims must be heard to be believed and the action moves at a nice pace. If you're a fan of blood and gore, then this film won't satisfy your needs, but if you like quality acting, directing and a decent story-line, then this may just be what you're looking for.
