first of all i love pretty explicit and audacious lesbian vampire flick vampyres ( 1974 ) and but more rare and obscure symptom be even well and certainly different in tone . it a very subtle and calm and restrained horror film with plenty of mysterious atmosphere . helen ramsey arrive back from switzerland to her old fashion family home and accompany by a friend ann west . it quickly become clear that helen suffers from a nervous disposition . at night both helen and ann hear voice in the house and helen seem convince that there be something in the attic and a trap door to which be in the ceiling in a corner of her room . symptom be a genuinely frightening horror film about a woman slowly slip completely into madness . the cinematography be strike and the interior set be terrifyingly dark and the acting by angela pleasence be fantastic . i fell in love with this film and can not praise it enough .
