Two points here really: there’s nothing quite like kicking off your film with a story about the simultaneous death of 3 billion people to raise the narrative stakes, and intimations of the coming apocalypse are best made in Mexico during heavy winds. Viene una tormenta!
 
Lesson for McG: That along with incredible action sequences and pithy one-liners, the general tone of the film should be one of overwhelmingly grim fatalism.
