There is a famous Einstein quote: “If you can't explain it simply, you don't understand it well enough.” In my opinion Nolan failed to explain it simply. Oh don't get me wrong I loved Inception, Interstellar and Dunkirk even though TBH I didn't understand Interstellar fully.
I had great expectations from Oppenheimer, I wanted to watch it first day as it is about Manhattan project and Nolan made it. But I am disappointed as the move is all over the place. It fails to catch audiences' attention throughout the film, even I wanted to focus and try to understand but the movie was all over place. There is no doubt Cillian , RDJ, Emily and others were great in the movie, they are all great actors, but according to me the movie the fell short of what we expect of Nolan. From Nolan we expect our intellect joy and mind blown but nothing happened as such instead I got bored in few scenes.
