Maybe I'm too literal to appreciate this movie, but...

Rating: 5/10 (27 October 2019)

First, the movie is simply too long. Second, so many unbelievable scenes, such as:
When the rich family goes camping (completely unbelievable) the poor family parties in the rich family's living room spilling food and grain alcohol everywhere. When the rich family comes home unexpectedly, they hurriedly sweep the food and spilled alcohol under the coffee table. How can the rich parents sleep on the couch two feet away from this mess but don't see or smell any of this - especially the husband with the fabulous sense of smell? Or at the very least smell the stinky family who are also hiding under the coffee table?
Poor family's home is flooded by sewage and rain water due to a deluge. The family goes home to try to rescue what they can, wading thru chest high sewage water in their house, but nothing is salvageable except the rock. That night they sleep in a shelter but wake up the next day dry with not a trace of filth on any of them. Oh, and their phones are still charged and work. I guess they were on their heads. And then they go directly to work at the rich guys house for the son's birthday party. The daughter in a lovely dress. The son in nice clothes. The dad in his chauffeur uniform. Huh?
Scenes like that make me crazy...
But I did like the fact that the first housekeeper was as corrupt as the poor family. That I didn't see coming. Or the Quentin Tarantino ending.
