Thus concluded MrsD.'s "Best of Belgian film festival", this one was rated #1 (by whoever rates Belgian cinema I guess).
Another, equally superb Dardennes-helmed project we watched was The Son, with a similar plot involving the troubled paternal relationship between a man and a teenage boy.
Her other two picks were "Bullhead" (the tribulations of a rural, steroid-addicted castrato) and "Jeanne Dielman, 23 Quai du Commerce, 1080 Bruxelles" (the tribulations of a widow/mom of live-in college student son/secret prostitute/fastidious housekeeper).
Fantastic series!
