California crumbles in San Andreas, an overblown, preposterous and only intermittently entertaining disaster film that benefits considerably from Dwayne “The Rock” Johnson’s proven screen presence. In the aftermath of a devastating earthquake along the San Andreas Fault, rescue pilot (Johnson) and his estranged wife (Carla Gugino) reunite to save their daughter (Alexandra Daddario), who’s trapped in the middle of San Fransisco. The initial impact of San Andreas is impressive, as the power of earthquakes to flatten buildings, people and whole cities is demonstrated through enormous, sweeping special effects wizardry. But once the dust settles, a script free of emotional and depth comes into view. The performances elevate it somewhat. Johnson is as watchable as always as buff helicopter pilot turned caring family man Ray, whilst Daddario manages to combine sexiness with actual survival smarts. It’s never enough though, and there’s always a corny line or banality (the shoehorned in backstory has been done much better elsewhere) around the corner to reiterate how dumb and worn out San Andreas is.
