Someone, somewhere, hits the “Enter” key, and a nuclear reactor in China explodes. A similar attack against the U.S. fails, but when the same hacker causes minor havoc on the stock exchange a joint American/Chinese task force is formed to locate and capture the cyber bully. Captain Chen Dawai (Wang Leehom) insists that they need the assistance of a currently imprisoned hacker named Nicholas Hathaway (Chris Hemsworth), and soon the team — which also includes F.B.I. agent Carol Barrett (Viola Davis), U.S. Marshal Mark Jessup (Holt McCallany) and Chen’s sister, Lien (Tang Wei) — is trotting around the globe in search of the criminal mastermind. Hackers haven’t exactly had the best track record when it comes to being central to a film’s plot, and the great ones can be counted on one hand — WarGames, Sneakers, ? — so newly announced titles are often greeted with understandable hesitation. The news that Michael Mann would be tackling the topic created something of a conundrum — sure it’s a movie about frenetic keyboard slapping, but it’s from the director of Heat, Thief, The Insider and Collateral. So it could still be good, right? Hell, there’s a chance it could be great! Well thankfully all of that hand-wringing can stop now. Blackhat is most definitely terrible.
