My Son is an unusual film; it was made with a specific approach in mind. The lead actor, James McAvoy, who plays Edmond Murray, wasn’t given the complete screenplay. He had to improvise his lines while the rest of the cast knew their parts—a curious method. But did this technique prove successful? We'll discuss that further in our detailed analysis. It’s clear from the outset that My Son isn't a standard thriller, and viewers will appreciate the beautiful scenery of the Scottish Highlands. The film focuses on themes of justice and an alternative perspective on it; we'll elaborate on this later. The narrative follows Edmond as he returns to his former wife because their son has gone missing. As the police begin their investigation, various aspects of the characters are revealed alongside some concealed truths. Their son is lost among many other boys, and both we and the authorities are eager to understand why it was him—what occurred? How will Ethan’s parents cope with his disappearance? This thriller raises numerous questions; will we find any answers? You can read our full analysis at https://www.spotamovie.com/my-son-movie-review-and-explanation-2021-movie/.
