How many deranged people can you fit into one movie? Let's see. You have:

The philandering husband The above husband's wife The above wife's sister

And get this? They're all related.

Then you have a nanny that can't keep her mouth shut and feels she needs to stick her nose in other people's business and blab it out to anyone who will listen. Can you make ANY decisions on your own?

And the nanny's boyfriend, who apparently is the "voice of reason", gives her literally the worse advice ever - advice where she would likely lose her job or her life - yet she keeps going back to this guy for advice.

And when these ppl need to go into hiding, here are 2 tips: Find a place or hotel by yourself Don't let anyone know where you are.

Then apparently everyone was stalking everyone unbeknownst to everyone.

And, finally, why did the wife need to kill the nanny and her boyfriend. She had already achieved her agenda very anonymously and was on no one's radar.
