“We All Fall Down” (* out of four) was a boring post-apocalyptic thriller about a young man (Cardiff Gerhardt) who struggles to protect his mute younger brother (Connor James Moore) in a desolate world in which all adults have turned into zombies and a cannibalistic tribe begins hunting them down. Cheapjack pastiche of “Lord Of The Flies”, “The Walking Dead”, and also “The Road Warrior” but completely lacking any of those film’s grandeur or thrills. Perhaps it’s time to give these futuristic and apocalyptic stories a rest for a long while.
