Rating: 4/10 (13 October 2017)

Essentially dire. Terrible script, no story line, and laughable action scenes, e.g. police stations built completely out of brittle glass, or massive street destroying explosions from small packages. Hopeless. My wife and I were so gripped by this film that I'm on the computer writing this review and she is using her smartphone.
You can cant live this time again, don't waste it watching this.
