I liked the choice of having medium and close up shots most of the time. I also liked that the co-director/real wife didn't act in this film and represented herself through another actress. That decision worked well with the what was being said about the couple's relationship. Enjoyed every minute.
Awkwardly confessional in a distancing/annoying way that eventually wears you down and you end up liking and admiring the film at hand. The fact that Moullet's girlfriend (& co-writer/director) would not appear as his on-screen girlfriend tells you more about their situation than the constructed reality of 'Anatomy of a Relationship' ever could.
