Allegory is a dubious friend to monster movies. Take The Mist, for example. When you’re telling the story of Mans’ struggle against giant man-eating insectoids, you don’t always need a political subtext. To be frank, I think most tales of claws, teeth and twitching antennae are better off sticking with gore. It’s the 50s fault. If it hadn’t been for McCarthyism and Invasion of the Body Snatchers, there would never have been a precedent for B-movies with socio-political aspirations. After Body Snatchers, it wasn’t enough to have the bug people gnaw our limbs off and tear young women’s blouses; they had to be (Shock! Horror!) based on something.
