All those saying 1 star reviews don't understand the movie they're going to see. It's not some action movie with car chases and gun fights. Imo Nolan does an excellent job creating a entertaining movie about one of the biggest events in history, perfecting the balance between physics and enjoyable dialogue. Crosscutting, one of Nolan's signature film making techniques, is used to flip between the far past, near past, and future. It does an excellent job to keep the film entertaining. Nolan portrays openheimer as a flawed character, not as some dainty joyous american hero, which gives the movie credibility to being accurate. 10/10, already watched it twice
