Just saw this with the wife and it was sold out. One thing I picked up was the vivid detail that the father went into about the deer, I could tell that made chris uncomfortable because he could see the double meaning.
I didn't pick up on the grandfather/grandma angle until the end but it all made sense.
The movie was brilliant and had so much innuendo that it makes you think about the liberal "affluent" whites being worse than the open racistmake america great again whites who troll on social media and in real life. Maybe there isnt a shade of grey.
Lastly when the guy nose starts bleeding and he tells chris to get out, it seems the maid was about to say the same thing but she couldn't formulate the words in the bedroom scene. So many little things that were easily missed.
