Absolutely no believable story line. The characters were too obviously sinister from the beginning but this just got more ridiculous as the movie went on. Neither were the characters likeable. Nothing original about the basis of the plot really. Rich white folks being mean to black folks. Apparently if you are rich and white and employ black people to work around your house you are racist. Hmm- what do we call rich white folks who employ other not so rich white folks to work around the house....?
Don't know how or rather why this film got the ratings it has except that maybe its too easy for people to be entertained by drivel.
