After my third screening I can pretty safely say, this is my favorite Nolan movie I have seen until now.

Through breathtaking cinematography Hoyte van Hoytema delivers the best (and most beautiful) argument for the return of practical effects and analog movie making in recent time. Exactly those striking images of men talking in rooms or atomic particle effects are elevated even higher through the incredible tactile soundtrack from Ludwig Göransson. Always dancing perfectly on the thin line between genius and disillusion, we can feel the underlying, creeping darkness that coats the ingenuity of Oppenheimer.

This twisted nature is even more apparent in the infinite blue eyes, the somber look and facial experssions of Cillian Murphy. It feels like he has literally evolved into that very man, that character in the process of filming. But also the rest of the cast most prominently Emily Blunt, RDJ, Florence Pugh, Matt Damon, Benny Safdie, Jason Clarke, Josh Hartnett and oh so many others help to elevate this movie from a biopic into more of a character study.

And thats why the epochal "Trinity" scene is not the most challenging, striking or boldest part of the movie, but the incredibly visceral - but in comparison - quiet scene right after. Oppenheimers inner workings are layed open to us with bare hands, completely stripped back. His underlying feelings about the ways we as humans are and act, our confusion and our paradoxical nature shines through for just a few seconds.

And here lies the real genius of Nolan. How he can use metaphors and imagery in his movies and stories to link them to even bigger themes and questions each and every one of us can feel. Connecting the micro with the macro. 
In Interstellar gravity was the metaphor for love. Now in Oppenheimer, the uncontrollable atomic reactions are juxtaposed against the interactions and emotions of humans and their consequences for our personal lifes, as well as our entire species. Just like atoms, we as humans also repel of each other. We split and fuse together again or we combine one another to create something completely new.

To realise that humanity in itself is exactly that uncontrollable chain reaction just waiting to explode, brings turmoil with it. But to be the single waterdrop that drops onto the sea, giving motion to that reaction, has to be an unfathomably feeling of guilt.
