Very good thriller, sharp and dialogues are mostly well written. Rosamund Pike is great as a psychopath. But, in fact, the movie is a faithful portrait of normal, everyday family relations only over-dramatized for the screen.
Yet, as in "Yellow" Hollywood producers have a strange view of a lifestyle of ordinary American. Community college adjunct and part-time blogger live in a grand, 4+ bdrm. house.
Another of their biases--correct as I suspect--is that hicks, no matter how friendly they might look (I mean a girl in an apartment complex who "befriends" a heroine and her boyfriend) are all money-hungry thugs inside.
