P1H starts off well but quickly looses any sense of thematic and narrative based cohesion. The opening story of a dystopian world, where people are intentionally infected with a deadly virus by swarms of mysterious drones, is actually pretty decent. It builds on this idea nicely before abruptly jumping back in time. Suddenly we have two new characters, who look and behave, like refugees from a Korean boy band. Oh and apparently they have device based, super powers. The net result for the viewer is unsurprisingly, cognitive dissonance in abundance and the dissipation of the atmosphere and tension, established in the first quarter of the film. Unfortunately, this film never really recovers, shambling towards its untidy conclusion. In summary, when you have a good thing going don't screw it up trying to be too clever. The simple but entirely workable scenario this film established early on, could easily have been sustained and new elements introduced that would have led to cohesive story and satisfying conclusion. What a shame.
