In the current trend of zombies and walking dead's comes this idiotic and purposeless project of film. The creators of it probably were trying to convince potential buyers or investors to donate some money so they can produce a longer film but...nothing happened (insert sigh of relief).
One cannot feel satisfied with a five-minute short that doesn't know how to include three scary/thrilling sequences in it. We're thrown to characters running away from alleged zombies, with cops or military forces shooting them in the head, it's a huge mess. The comes the plot twist but it's so lame it won't get mention from me here.
Nothing to be seen here, really. If the idea was to develop something bigger, then more should be added. Characters, minor background story, intense sequences, and above all...the basics of a good script - character needs to go from A to B to reach C, internal and external conflicts in between. A weird waste of time is what we get from "Shelter 5". 3/10
