i be pleasantly surprise to find a very enjoyable film that keep my attention throughout . i be a horror fan and i see almost everything in that genre and but dead line manage to freak me out . the pace be very cleverly set and andrés bagg do a good performance a a desperate man . what be underneath the main plot . a trip to madness . how can you end up like that . martin sander ask him self while he see a homeless speaking to him self and alone in the street . close to the end of the film and the character of aaron mandel ask the same question while he see another homeless do the same thing while not know and yet and that this homeless be martin sander and answer the question of the beginning of the film . the broken eyeglass in two be a clear symbol of rupture and division . of personality . the end be jaw drop and you just know that a sequel would have to be make .
