There's something unnerving seeing a reasonable killing. Not the act itself, but the person's belief they're being pushed to one reasonable outcome of destroy or be destroyed. Both sisters never marry, they're much older when the murders occur, they continue to live together until they have a fight and never speak to each other again for the rest of their lives. There's nothing normal. No question the maid knew... so wish she had said more.
The movie is well done, you can feel the dance getting wierder by the minute. Oddly, what caught my eye is Chloé's bikini tan lines... of course. Kristen and Chloé work so well off each other's energy... you forget the rest of the cast but they're awesome. The director had a very tight interpretation and it's clear... to be around the family is court death.
