Loved the wood chipper ...

This movie is so ridiculous. How could these Vesps or whatever they are
called exist? There are animals that evolutionarily diverge and lose their pigment and their eyesight, and end up living off insects, or fish in caves and such, but if these things were trapped in an enclosed area for thousands or millions of years, first - what would they breathe? Then, what would they eat? And if they are adapted to eating fungus, or insects, or even fish, how could they have teeth for ripping humans apart. But, even if there was some kooky explanation for all of that, wow would there be such numbers of them that they would threaten the whole world? Crazy movie ... 3/10
