Oppenheimer
Love and enjoy every second of this 3 hour masterpiece. Cillian Murphy definitely deserve Oscar.
Edit:
Rewatch, I'm so happy about Cillian's Oscar!!! The second viewing was just as good as the first. This time, I watched the film with my parents, and they weren't entirely convinced by the third act. After watching it a second time, I noticed even more nuances and consider it one of Nolan's best works.
