Shrews are tiny little rodents with a slightly amusing name.  Who thought it would be a good idea to make a film about how terrifying they are?  Apparently Jay Simms did, as he wrote this.

The special effects really let this one down.  The giant killer shrews are obviously just dogs with rugs thrown over them, and the model used for the close-up is unbelievably bad.  I did like the shrieking sounds, though.  And how can you not love a film which contains the line "The shrews were out there!  I couldn't take the chance!"

Also:  I presume the word "What" is missing from the very start of this trailer.  Although as it stands, "Could be more terrifying" is a fairly accurate description.

Favourite bit:  The close-up of the Killer Shrew's face as it comes through a door.  Classic.
