“ANATOMY OF A FALL” (2023): what do you need to see and understand in this film?

“Anatomy of a Fall” by French director Justine Trieu is a film for an attentive, not lazy viewer who is ready to notice not only many clues, but also their frequent contradiction to each other. Some plot clues seem to come from the prosecution. Other clues appear to have come from the defense of writer Sandra Voiter, who is accused of murdering her husband. And the viewer seems to find himself in the role of one of the jurors at this trial - he must either be convinced of the legality and validity of the accusation, or question it. But does Themis always have to be completely blind?
Let me add that the film “Anatomy of a Fall” has already received the Palme d’Or at the Cannes Film Festival in 2023. And now he is nominated for an Oscar in 2024.
The role of the main character Sandra Woiter was played by German actress Sandra Hüller.
