Two big clues -- it was on SciFi, the channel that will be bringing us "Man-Thing" and is already responsible for a couple giant snake shows. Secondly....well, it just looked dumb. For good end-of-times scares, there's an old movie about Christians being herded up and guillotined when they won't get the mark of the beast. Can't remember the name, but it's from about 1980 or so, so it has that grainy, spooky 70s look.
