This crime thriller/revenge action film is a straightforward story about a guy from South Africa who comes to LA to find his sister, only to learn that she was viciously beaten and murdered. He spends the rest of the film tracking down her murderers and learning why she was killed. He's easy to sympathize with; you will care about this man and what he's going through. The plot is steady and things are slowly revealed, enough to keep your interest. There is not a big plot twist at the end like some reviews have (for some reason) hinted at. Quite a bit of violence, but nothing gratuitous; it makes sense within the plot.
In sum, this film has good acting, it's a decent story, and it has a plot steady enough to keep your attention. Perfect for Netflix and chill.
