The movie was good to the beginning and middle when it focuses on Oppenheimer and the nuke (more specific, the Atomic Bomb.) But towards the end of it, it just went on and on and on and talking about politics and making it Anti-American, I almost fell asleep, it was just so boring. Definitely not one of Christopher Nolan's finest movies. But overall the movie was very authentic, and the dressing was cool and that was why I liked it. It could've been a 4 if it didn't do the stuff it did in the end. I do not prefer spending your money on this in theater depending where you live. My tickets were the most expensive thing since slice bread.
