This is one of the few, say past fifteen years, films with science and or high tech as an important plot element, whether sci-fi or just drama, that did its research and got the science/tech mostly right. And, it did so in a way that explained it with some entertaining clarity e.g. the opening, and a couple of other scenes, showing packets of data traveling through computer architecture was about as good as it can be. The rest of the film that dealt with cyber hacking was presented with accuracy and surprising clarity for a mass marketing film. Great location authenticity with filming in L.A. (OK, that's not so great), Indonesia, Malaysia, Hong Kong.
On the other hand the action scenes were basically just movie entertainment and at times a bit overboard. Such as, and a bit far-fetched, that our lead character (Hemsworth) is a world class coder (programmer) and some how had the time to become a world class action killing machine. Talk about being a Renaissance man! More of an international cast would have been interesting. Davis (with Tina Turner wig which made no sense for an agent) was stereotyped into filling the black FBI agent role which seems to be a popular character placement in film in recent years (e.g., recently, "Powers").
