The classics of this genre featured danger and destruction on a scale a guy could wrap his head around; a hijacked airplane, a skyscraper on fire, a capsized ocean liner filling with water. But when you live by spectacle, you die by it too. And so the disasters got bigger and bigger, one movie trying to top the next, until it became an arms race of planetary devastation. One movie blows up the White House, the next one washes it away in a tidal wave. Where do you go from there? An exploding tidal wave? At this point, if your disaster movie isn’t eradicating a large portion of the globe, don’t even waste your time.
