If you consider the concept only, it could have been a decent film, if it were more along the lines of the manga, Dead Tube, it could have further potential. With the first act, it seemed to be okay, if you ignore the poor aspects the overall set up is good, when the moral matters are brought up the message is overly played, really pushing a message, whereas if you took the concept to Dead Tube, you could have a successful message if not so on the nose, a message played through the events and what is seen rather than the ending that is given. Much of the overall film feels as though something exciting is about to happen but is unfortunately lost to draw in viewers to the the message the film and studio try to push. It is unfortunate this is a missed opportunity, the cast were also an issue in that they were selected for attracting a younger audience. If we had unknown actors, with a darker plot we could be left with something that makes the viewer consider what they have witnessed compared to the message that is painfully spelled out.
