This review may contain spoilers. I can handle the truth.
I felt like this film was sponsored by Twitter and Apple.
How on Earth would their iPhone batteries last for over 25 days and their phones not smash into a million pieces during it all? Also, how can they then still receive text messages at the end? When surely, most phone masts have been destroyed, due to the full blown zombie outbreak, and also, the WiFi is now magically reconnected and working super fast??
The phone engineers in this film, are the true heroes.
