“Edge Of Extinction” (** out of four) was a drab melodrama set after World War III in which nuclear holocaust has turned the world into a desolate landscape in which there is no more civilization and food and money are scarce; one survivor (Luke Hobson) stays alive in the countryside of Britain but soon is invaded and confronted by a terroristic enemy which threatens him and the state of the world. Nihilistic and bleak story offers moody and at times beautiful cinematography by Julian Hundy but we’ve been down this desolate and deserted landscape one too many times before (going all the way back to “The Road Warrior” nearly 40 years ago) and film is insanely overlong at nearly two-and-a-half hours.
