Some people have the ability to use only 3 neurons, one for eating, one for breathing and the other one for s**ting... This is not a movie for them...
But for those who enjoy using the brain... the whole movie is a metaphor, everything is there for a purpose, every single detail, the coffee mug, the red couch, everything... is a underestimated masterpiece...
It is hilarious, is raw and totally realistic, that's how we actually interact.... it is a royal comedy... total causality...
Just hang on, don't let the first scene shock you..... hang on... and enjoy the show....
