“BLACKHAT”

With his American and Chinese partners, a furloughed convict hunts a high-level cybercrime network across the globe. It’s a dim-witted, dullard of a thriller about hacking and terrorism for profit that has one saving grace: timeliness. Starring Chris Hemsworth, Viola Davis and Wei Tang. Directed by Michael Mann. (Cary Darling, Fort Worth StarTelegram) Rated R for violence and some language. At Regal Snellville Oaks . 2 hours, 13 minutes.
