Robot Overlords (Blu-ray release 2015-8-10) is a British sci-fi movie in which robots rule the world and people are imprisoned in their homes.  Several teenagers accidentally find a way to temporarily turn off the tracking devices implanted in their heads.

Even with limited budget, most of its effects are not bad.  This movie has the potential to be more entertaining, but in its current form it’s merely average.  The action sequences are less exciting and have less tension than recent action movies of similar subjects.  It also lacks proper explanations for some crucial matters.
