I like the double maid device. I don't think I've seen it before and it really works well. That said, it's about the only thing that does work. There are so many moving parts to this story that it defies the sense of narrative. Every time one conflict develops another is introduced, then another. There are now so many horrific things going on that its devolving into self-parody and camp. However, I'll keep watching it just for a glimpse of the young maid.
