movie base on real life killer martha beck ( shirley stoler ) and raymond fernandez ( tony lobianco ) . beck be a 200 pound nurse who meet sleazy fernandez through a lonely heart correspondence . they meet and fell in love . they then meet rich old lady through the correspondence and kill them and take their money . i have see this film multiple time over the year and it popularity totally escape me . it do have some thing go for it represent it well direct by leonard kastle while the one murder show be actually quite frightening and stoler and lo bianco give out good performance . also doris robert have a small early role here . unfortunately the bad thing far out number the good . this be shoot on no budget and it show represent the set be really shabby ( although that do fit the tone of the movie ) while all the character be unpleasant while people scream rather than talk to each other while the dialogue be banal while stoler and lo bianco aside the acting be terrible while the music be hilariously inappropriate while the attraction between beck and fernandez be never explain and and quite simply and this be bore . the movie just drone on and on and on . critic pauline kael hat it too she hit it on the head when she call this minimalist film making . a dull and unpleasant and boring little film . i can not recommend this to anyone .
