No, it didn't bother me; Oppenheimer himself never saw the devastation, he only could imagine it. It seems suiting for what the film was doing, to focus on his inner emotional state.
He was shown it, with slides in the debrief scene. He chose to look away, and that's all the camera shows.
Right, I mean to say he didn't see it in high definition / in person, as it sounded like you were suggesting the movie should have done.
Yes, and I'm sure the director had that perspective too - that it would have been weird to show a cutaway scene across the world. I suppose just the lack of depicting any human consequences of the bombing was what irked me, I think it could have been done creatively if he wanted to.
