Not too bad. Don't expect complicated supersmart hi-tech revenge from these ladies though. The best part of this drama, and also what kept me till the end was definitely the warm-hearted bond and friendship between the four. It's wonderful to see the strong emotional support system. Some of the revenge were interesting and funny as well. Although not brilliant, I did enjoy this, it was worth a watch till the end. Characterization was also good, each character, not just the main characters, had their own development.
