An absolutely wonderful experience to watch this movie (thrice) in theatres. I can see this masterpiece being able to cater perfectly for a good portion of its audience and possibly bore another; some people just want to see the bomb right away, but this movie is so much more than that.
I fall into the former category: the 3-hour air time was blissful, and I found the pacing fast considering the amount of history and content it's trying to digest. I have a simple physics background that allowed me to understand part of the scientific dialogue, and I realized you don't need to understand every bit of jargon to enjoy the movie. The movie's foremost intention, in my opinion, is to walk the viewer through Oppenheimer's visions, disappointments, internal conflicts, etc.
Perhaps that's not what everyone came for, but this movie exceeds expectations with its elaborate plot, top-tier cinematography and scoring, and thought-provoking idea about the true nature of the "chain reaction".
Oh, how could I forget about the cast? Cillian Murphy convinced me that I was watching a real-life documentary at certain times. Emily Blunt absolutely crushed her scenes, my favourite was when she testified and defended Oppie in her own way. The rest of the cast did an amazing job too. On my first watch, I thought the mature scene was unnecessary, but on my second and third watches, I begin to overlook its rawness and felt that it added to the tension of Oppenheimer's life, and how his life was essentially put on display.
Coming from a female high schooler, I think this movie has the potential to reach audiences of a variety of demographics; however, those who wish to enjoy this movie should walk into theatres ready to do some thinking of their own.
