Just one example?
The baby being slaughtered by the queens guards (illegitimate offspring of the king) in the first season is a perfect example.
Harsh. Immoral. Brutal. Gets everything it needs to explain across to the viewer and does it all off camera.
Shots can also be partial or glimpses instead of lingering and detailed (like the young prince's sexual-sadistic murder of the kind-hearted brothel girl).
Whole series is a sadists wet dream.
