The film is pretty enjoyable if you think of it as a police-themed action movie. If you expect some deep analysis of a society divided by races, social and economic status you will most likely be disappointed.
Throw a bunch of cop show clichés, and actors from previously cancelled cop shows, in a blender... and you have APB. Sprinkling drones, some tech gear, and a citizen crime reporting app on top is just lipstick-on-a-pig as it's nothing more than an old-style episodic crime-of-the-week series. Watch it fast before it disappears into obscurity.
