This Belgian series can be enjoyed without stopping. It tells how three sisters kill their brother-in-law because he is horrible to their fourth sister, to them, but to everyone. What we understand with each episode: the character is a terrorist and obnoxious with everyone.
The tone is black humor, with Flemish Belgian exoticism, and the film takes advantage of its length to develop a universe where each character has its dramatic arc to characterize him and his relationship to others, and of course his relationship to the ugly brother-in-law. With one of the dramatic arcs is the investigation that the insurers lead (the ugly brother-in-law had a life insurance, the insurer investigating, because he suspects a murder and not an accidental death).
The series and the script are subtly arranged so that it only explains at the very end of the tenth episode how the ugly brother-in-law died and who killed him, with all the previous time and different episodes used for various leads that make each of the characters may have a reason to kill him. As the series progresses, the possibilities increase.
This ensemble is served by a superb cast, led by the four sisters: Barbara Sarafian, Kristine Van Pellicom, Maaike Neuville and Ruth Becquart. The cast is one of the qualities of the series.
It is on this duration that the series format takes its interest, by diluting and multiplying the dramatic arcs. This is difficult to do on a film format of reasonable length (less than one hundred minutes).
