The entire film is based on a fallacy and therefore makes it difficult to watch. Ivy basis the documentary on the misleading notion that her grandparents are not guilty of being traitors. The facts are that her grandparents were spies. Later, her father Michael says, Julius might have helped the Soviets, but Julius did not do what the government accused him of. Then another person says Ethel was only being a loyal wife.
The film is a sophomoric effort to understand the dark stain on her family. The camera work, editing, and narration are all weak.
Ivy should have created a documentary on what caused the executions. It wasn't 'red scare', or 'communist witch-hunts'. It was because Julius and Ethel were spies for the Soviets. They are both guilty of betraying their country.
