i watched this drama long ago during the period that i was watching only mystery and crime shows. i watched it in one go since I am not someone who likes waiting that much and so i watched it all. It was interesting. the plot was rather good though it was every time the girl and the police officer trying to solve cases where the girl solves first and the other 3 sisters also help her. it has a few nice points as a drama and i would not say it is not worth watching. I think if you like murder cases maybe you should give this drama a try. however rewatch value... i do not know. i think it would be okay however you must reatch after you haver forgotten some things about it otherwise it won't be the same.
