Anyway, admit it, we’re here to see the Sistine Chapel come crashing down on thousands of screaming digital extras, or the Washington Monument totter and fall, or Caesar’s Palace tip into a fiery pit of magma (repent, ye weekend gamblers!). The attraction of disaster movies - which by definition have to get bigger and bigger if we’re still to feel them - is that they allow us to imagine our own extinction from the cheap seats, jolting us with spectacle, reframing our perspective, sending us home safe and sound.
