The sheer number of negative reviews of Hard Rain is an utter enigma. I've seen thousands of films, and own hundreds, and have a better than average comprehension of the cinematic arts than your average consumer, and I simply cannot find whatever it is that triggers the peculiar neurological anomaly in viewers who complain that Hard Rain is "boring," or it's plot "convoluted." While the cast does barely manage to land just below the maximum level that a simple heist picture can bear, before the audience begins to lose track of who is who, it's a credit to the director that none of the characters becomes anonymous in the dark and the deluge.
HR is a taught and relentlessly paced action film that hits the ground running the instant the opening credits fade from the screen, and barely pauses to let you catch your breath before the final credits begin to roll. If you have time to get bored, there's something seriously amiss, see a doctor immediately. While there may not be any spectacular stunts that you've never seen anywhere before, the stunts abound, and the chase is nonstop - as is the torrential downpour and the rising flood - this story is so dark and so wet, you may feel the need to towel off several times before it's over. Of course there are implausible escapes, you can't have an action movie without impossible hair-breadth narrow misses every few minutes, and cynical characters double-crossing each other, and guns that never empty - until it's convenient for the script writer (the same mind who brought you 'Speed' and 'Broken Arrow,' no less, also top notch breathless actioners).
What you won't find, are long monologues, existential angst, or nuanced character development. These people are pretty much what they appear to be the first time they're seen onscreen. They don't grow, or wisen, or mellow with time. They chase and try to kill each other. There are a handful of decent human beings, a whole bunch of greedy A-holes, and some old folks for comedy relief, and it's not hard to tell who's who. But if Hard Rain doesn't keep you glued to the screen from beginning to end, adjust your meds and watch it again. It's not the movie, it's you.
