Haven't watched any Desplechin, yet but if I'll try some in the future it will be Kings and Queen. Missed it at this years french film festival, though I'm more annoyed that I didn't watch Assayas' "Clean", or de Broca's last film. 
Ah, "My sex life... or how i got into an argument" was also shown sometime this year, as one of the films honoring Jeanne Balibar. I idn't wath it, but would have been more interested in Mathieu Amalric, I must confess
