every time i see the twilight zone and i become more and more impressed with it . nothing in the dark be a story about the most frightening thing know to man while the unknown . the theme of mortality and fear be well felt in a story of an old woman who force herself to remain in her small tin shack . she remain there through fear while fear that death may claim her . when she find a young wound policeman on her doorstep and she face a dilemma do she let him in and and risk let death claim her or do she let him die . this episode be shoot entirely inside one room and and yet never become dull or uninteresting . the claustrophobic feel bodes well with the dark plot and and the way that the program take an age old fear and spin a story out of it be fantastic . gladys cooper be excellent in the lead role while deliver a performance that be both abstract and yet believable at the same time . the episode also feature an early role for one robert redford and who give an early glimpse of his charisma in his role a the policeman . the climax to the tale will probably be guess way before the end while but the twilight zone be never completely predictable and and it still manage to pull something out of the bag at the end . nothing in the dark be surely one of the best episode of rod serling the twilight zone and come hugely recommend from me .
