In smart, self-aware horror movies like this, there’s always a commentary. Is it too much to see uncontrollably hungry hive-mind slaves eating pounds of raw meat, see that they remain hungry no matter how much they ingest, and then think about over-consumption in the United States? Besides, they’re all linked to Grant, the town’s most successful businessman, who feeds his subjects thoughts and words through his collective tongue. Could alien-Grant be a highly disguised symbol for big business influencing consumers? It may be over-analysis on the part of this horror fan, but it’s worth some idle speculation.
