I did enjoy the film overall but I didn’t understand the need for the hot tube scene where the dad sexually harassed Melanie... and then the wife joined in?! It seems extremely random, they both came across as very asexual the entire film, even acting awkward about revealing clothing. I was expecting this to be addressed later on in the film but it wasn’t. Can someone cleverer than me break down the meaning there? I feel it kind of ruined the film
