Liked it except one point in the story which soured it a bit for me.
Since since was a vital moment in the movie, i thought that this moment could have been written differentliy but with the same outcome of the rest of the movie.Why did they (Kim's) let themself get pressured /blackmailed by the former housmaid and her husband with the vid? They had dirt on the housmaid too, she had her husband living in the basement for 4 years and while they hadn't any videos of it, it would have been easy to proof this, since the basement is right there. Instead the were sitting there with their hands up like the former housmaid had a gun trained at their heads. As far as i see it, it was rather a stalemate situation.
Because the housemaid didn't care if they had dirt on her. She even said that once she sends the video they'll all go to jail together.
Anyhow, what a crazy movie. Emotional rollercoaster.
