The inciting incident (the nuclear power plant breach, which was shown in the trailer) isn't actually particularly farfetched. Last year hackers did serious damage to a German steel factory by hacking with the controllers to a blast furnace, which melted down. The Stuxnet work destroyed a whole lot of Iranian centrifuges around 2010 (meta-source). Most of the rest of the hacking shown is phishing or social engineering, most of which is technically reasonable (though if I were designing a bank's network, I would not connect the machines at the front desk to the financial systems).
Unfortunately, the plot wrapped around the hacking is not nearly as reasonable. The main characters all suffer from Jack Ryan Syndrome, in which an analyst or other technical asset suddenly turns into a competent field agent, including the ability to make long-distance pistol shots while under fire better than trained assassins. Nearly everything about who they are and what they do strains credulity. The villain has no motivation beyond "crazy" - and while that can be done well, this is not. The romance subplot is laughably bad. Wei Tang does a fine job of acting the character which was given to her, but that character exists in the plot for the sole reason of being the romantic interest, which is pretty pathetic. None of the other performances are worth mentioning, mostly because the characters aren't interesting in the slightest.
Blackhat is 2 hours and 13 minutes long, and I'm not sure why. I think there might have been about an hour and a half of plot, maybe an hour 45 if I'm generous. Nearly every shot lasts ten seconds or so more than it needs to, though, which makes the movie drag terribly. Some of those shots are completely out of focus for no reason whatesoever. Action movies should not be boring, but this one is.
Worst of all, every single shot is so shaky that the movie is almost unwatchable. Long-time readers will know that I am not a fan of shakycam; this is some of the worst I've seen. Even in shots with no movement, the camera waves around nauseatingly. Action scenes are far, far worse.
There is no reason to watch this movie unless you're a hacker, want to see how bad it is, are seeing it for free, and want a headache.
I take solace in the strong possibility that every movie I see for the remainder of the year will be better than this one.
