i guess it is bc the writers haven't explored any other concepts. even if they do try something new, thye end up going back to the same thing, cuz they know that their veiwers r used to seeing it. then they are afriad to change the story due to the fear of losing viewers. thas jsut a guess. im not sure tho u know. as i'm just a viewer. but i agree it is so dumb that they have a really bad person n a realy good person. now i mean i would act really good if someone took everything of mine just so they think that im not up to anything and then at the right time, turn everything around, u know thas how i do. hah jk :P
