Take the time to understand the movie first. You will begin to appreciate it then. It is slow, sure. It paints Oppenheimer as the sole reason we created the atomic bombs, which is just incorrect. I believe Cillian Murphyโs portrayal of Oppenheimer was outstanding, best in recent memory. Itโs a dramatic historically based scientific movie with a big budget, of course there will be concepts you donโt understand.
