Oppenheimer
Watching this in theatres were one of the best experiences ever.
The intense building up in the atomic bomb scene, waiting for the audio to travel to the audience - and when it does, it is absolutely mind blowing, no pun intended.
Great cast throughout. Christopher Nolan did a great job with the practical effects, the best director.
It is a slow movie, but it explains an atomic bomb well and made me pass my chemistry and physics national test.
