I think Hard Rain is a really good film. Nice twist in it half way through from what I remember. Anything with Morgan Freeman in is worth a watch as far as I'm concerned. And of course you're right about the greedy politicians, they're all the same.
I seem to recall that once upon a time the idea that turned into Hard Rain was actually meant to be a typical Sylvester Stallone vehicle (called something like Galeforce or Stormfront), but clearly that never worked out, and the result is all the better for it. If you bear in mind that Stallone also turned down the role of Joh McClane, he's certainly done us a few favours in his time.
