After having watched all of Nolan's great films, such as Interstellar, Inception, Tenant, and the Dark Knight trilogy, you should not expect Oppenheimer to be similar to those movies. This time, Nolan has challenged himself with a biopic, where fiction does not overthrow the accuracy of events and characters. Oppenheimer is a completely different film, spanning three hours and featuring some scenes in black and white. It may be perceived as boring and even torturous by many due to its unique focus on Oppenheimer's life the father of atom bombs who lived a significant and terrifying existence. The movie centers on court-room drama, deep thrilling conversations, and brilliant dialogues with an outstanding background score. While I had certain expectations, the movie immersed me in its actual presentation, guided by the excellent performance of Cillian. Oppenheimer won't take you to outer space like Interstellar or into dreams like Inception, but it will give you an intimate experience of J Robert Oppenheimer's life and the guilt he carried, while posing unanswerable questions. The primary motive of the movie is to allow the audience to see and feel Oppenheimer's life in the closest way possible.
