The difference is that in the movie, it is a single bad guy (well, a small team of bad guys anyway). The story is different when it is a country orchestrating the attacks. Do we launch nukes in retaliation? Do they follow up their cyper attack with a nuclear attack? Or even just a coup? I'm a lot less worried about loosing all my money to some crook than I am to the US being overthrown (even if the government is just full of crooks)

I'm a lot more worried about the US overreacting to a cyber attack, or reacting to a forged country of origin. That seems much more likely than overthrow of the government. The day the US government said that cyberattacks could be considered an act of war, I'm sure there were numerous smaller countries and non-state actors scheming ways to make it look like Russia and/or China wiped out the US financial, government, military, and SCADA computer systems, triggering a physical war. It's kind of like the supposed automated USSR doomsday retaliation scenario, except anyone can pull the trigger.
Down votes for referencing a movie?? My point was, if even Hollywood has already covered this then it is a long long way from a new idea and not exactly 'news'...
