Blackhat is the worst kind of movie. A boring one.
Even with Thor nonchalantly dressing or undressing seemingly every ten minutes it was a struggle to get through this. In fact, discovering that the Blu-Ray itself was transparent was far more interesting than any of its contents.
Hemsworth is wasted, large portions of the story are painfully obvious and it drags on for too long. Only Swordfish has made hacking remotely tolerable, and that was because it was ridiculous. Here we just see horribly dry brogamming.
Watch something terrible instead. At least it will give you something to talk about.
