Hard Rain is one of those movies that never convince you its stories are really happening. From beginning to end, I was acutely aware of actors being paid to stand in cold water. Suspension of my disbelief in this case would have required psychotropic medications.
Oh, the film is well-made from a technical viewpoint. The opening shot is a hum-dinger, starting out with a vast floodplain, zooming above houses surrounded by water, and then ending with a closeup of a cop s narrowing eyes. But even then, I was trying to spot the effects to catch how they created the flood effect, and how they got from the flood to the eyes.
