The U.S. could never make a film like this
I thought this was an extremely intelligent, nuanced, thought-provoking movie exploring the subject matter of nature vs nurture...it didn't exactly break new grounds, but I just found it masterfully well written and presented, the perfect example of a story-driven film.
What was very surprising for me is that for the first time ever I was pulled into a line of thinking that I generally really disagree with and never thought I'd adapt - but in essence, this is a type of movie that it would be impossible for Americans to make, or at least Hollywood.
Why? Because it lacks any and all exploitiveness.
If this was Hollywood, dear Lord. It would be sexed up like crazy. The two couples would be screwing each other constantly, showing us how they are different sexually as well (this movie managed to do that perfectly fine without graphic bedroom antics) ; there would be an affair; there would be nudity, I mean you name it. Americans need sex to keep their audience interested in a subtle plot. The "progressive" libtards would then defend any such criticism with "u prude its just natural tahts what couples do brah", but the uncomfortable truth they can't face is that they rely so much on sex in their movies because often they can't allow a story to stand on its own.
Or alternatively there would be an abduction. One of the kids would get kidnapped, there'd be a car chase scene, there'd be violence, etc. again - no Hollywood producer would just allow a film like this to be put out without sex or violence.
Excellent acting in this movie too, and the children were completely natural - 99% of other times when children have major roles in movies, they are depicted as witty smart-asses a good 10 years above their actual age.
