Dramatic events continue in a series of interesting episodes beginning with events where a group of thieves kill a security guard who used the APB application before his death; Gideon restores the design of the chair for use in the interrogation room. But Murphy knows her ex-husband is watching her. Brandt's own mission is to capture criminals who sell armor piercing bullets. A task force led by Murphy's former husband threatens the future of Gideon.
APB is just an empty, run-of-the-mill cop show that separates itself from the hundreds upon hundreds of previous TV cop shows by having an app that citizens of Chicago use, thus circumventing 911. That's not an advancement of the genre - it's just stupid.
APB never settles its own version of its existential dilemma: man or machine? It argues for both. But as this uninspiring drama proves, sometimes when you split the difference, you end up with nothing.
The "good, dumb fun" approach doesn't really work for a series that's so steeped in real-world problems. Subject matter like this demands a more nuanced, thoughtful approach.
