Just under your feet lurks an evil so deadly, so intelligent, it is scary. The attendees of an ecological summit are about to discover a bigger problem than global warming.
The plot reminds me of "Phantoms", but that may just be me. The film itself clearly has no relation to the Affleck masterpiece. This one is clearly more ecologically-based (and they never stop mentioning tree huggers, global warming and more -- they tried too hard).
What does it say when Kevin Sorbo is the only "name" actor? Maybe nothing, as lots of great films have unknown actors. But when you are seeking a mild celebrity and the only guy you can get to sign on for the project is Sorbo, that may not be a good sign for your movie. (I should stress this was not meant to knock Sorbo, who is quite good in this film. He is just not a name that generally draws in crowds.)
This was definitely intended to be humorous -- right off the bat, there are jokes about a dead guy and the line, "Days without a workplace injury -- zero." I appreciate that, because if you cannot make a scary horror film, you may as well make it funny.
