Hi Charles - I certainly don't intend to condescend. Obviously that article was written not in response to you personally, but as a general response to some of the other criticisms. But on balance, perhaps it doesn't address your specific points, so I'll attempt to do so here.

1. The "most important man who ever lived" line is from Strauss, and I agree, I wouldn't make that claim. I don't think Oppenheimer would have made it either. But in the context of the film, it works dramatically from Strauss.

2. I'm not a scientist, but I don't think this is really a film about the science per se. That is more background detail than what Nolan is concerned about here. Rather than directly focus on the minutiae of expert project management (this film isn't a corporate seminar, thank God), who replaced who on the project, and the other scientific stuff you mention, this is a film about universally relatable themes such as ambition, obsession, whether brilliance makes up for other shortcomings (his womanising tendencies, for instance), and of course hubris in his because-we-can attitude that he later backpeddles on when opposing Teller and the development of the H-bomb.

3. The brilliant use of close ups you mention provide a sense of being inside Oppenheimer's head and thus one feels (or I felt) the claustrophobic, crushing sense of guilt he felt after the bombing and what he'd unleashed on the world as he urged to put the brakes on the arms race. Sadly, he wasn't listened to, and his subsequent persecution by Strauss at the height of McCartyism gives the film a poignant, tragic, dramatically satisfying rise-and-fall arc (in the intercut timelines) that emphasise the Prometheus metaphor to quite brilliant effect. I think both aspects of the film - The Manhattan project and the McCarthyist aspect - build to a devastating climax (the bit with Einstein) that I actually found quite emotional (I know some people didn't, but I did).

As another point of comparison, this film reminded me of two other recent-ish films - Jackie and First Man. The former is about Jackie Kennedy's grief in the aftermath of the Kennedy assassination. Lots of detail about the political background isn't included either because it is best covered in other films, but it emphasises, superbly, what I'd again call the claustrophobia of grief in the use of close ups. As for First Man, that isn't really a film about the space race (unlike, say, The Right Stuff) but the man on the moon as grief metaphor thing works beautifully. It's an achingly moving story of a man coming to terms with the loss of his daughter. That man just happened to be Neil Armstrong. I love that film too.

In short, I think Oppenheimer is brilliantly acted, written, and directed, with all the above in mind, and I firmly stand by my opinion. Obviously, other opinions are available. There are different films that can (and should) be made about all the other aspects, but I think the focus Nolan chose he delivers on brilliantly.

I hope that responds to your (perfectly valid) thoughts a bit more coherently. Again, I certainly didn't intend any condescension. :)
