Savage Creatures

It takes a little while to realise this film isn't to be taken too seriously, but if you allow for the ludicrous plot, it is certainly worth watching. It begins with a bit of misdirection: a woman and her son have kidnapped a young woman; taking her home, they murder her, chop her up, and...yes, they're cannibals. Shortly, they see two teenage girls/young women walking alongside the main road and offer them a lift. Thinking they have found two for the price of one, they take them home, drug them, and while mother goes shopping, son is left to prepare them for the freezer. He puts the first one in the bath and chops off one of her hands. And this is where the fun begins. They are vampires, four centuries and more old, and, it goes without saying, don't take too kindly to being drugged, much less butchered. But can they save the world from the invading aliens who are turning the locals into zombies? What do you think?
