I'm really into this topic, so my response might be kinda long and full of personal opinions.
1. That scene when David Hill shows up in court and totally checkmates Lewis Strauss? So damn satisfying.
2. And then, when Strauss loses and his underling (sorry, forgot the name) is like, "Maybe they ain't talking about you, but about something way more important." Classic move!
3. Oppenheimer and Jean Tatlock's scene? At first, I thought they'd just be together, you know, simple stuff. But damn, it got so complicated and twisted. Oppenheimer even got tagged as a commie 'cause of Jean. But in the end, he chooses Kitty. Shows even a genius like Oppenheimer can go all mushy when love's in the air. Totally relatable to our usual lives, haha.
4. When Jean dies and Oppenheimer's a total wreck, but still keeps his head in the Los Alamos project? That's some next-level handling.
5. Kitty standing up for Oppenheimer in court? Badass move, seriously. She ain't just "Mrs. Oppenheimer," she's got her own intriguing character.
6. That part where Kitty can't handle her kid due to stress? That's like a real-life thing for all the moms out there. Rare to see a movie tackle this.
7. The bomb testing scene? Straight-up awesome, no doubt.

So, that's like a quick rundown, but seriously, I've got way more favorites if you're down to chat more.
