I liked it, but it was kinda two movies mixed together. In the beginning, we see a bit of all those hearings and stuff, his early beginnings, ad then a long part mostly focuses on the Manhattan project, and then we focus on the politics and communism allegations.
The trailer focused more on the bomb and the project leading there, and I kinda was looking forward to that the most. The hearings and stuff actually though had a good dramatic arc, I think, though I still wonder if it shouldn't be two seperate movies? But perhaps not, because it's all part of who Oppenheimer was?
