Short recap: Sisters take turn blaming each other for everything that goes wrong and neither will look in the mirror

Long version: At some point, even the writer grew tired of these sisters and kept throwing one twist after another to try move the story forward. Even the writer was swapped and the new writer killed off more characters. Randomly new characters would pop up from nowhere to replace a character that was killed off. Towards the end, the writer was obviously just trying to figure out how to drag the story to fulfill their contract.
