"Oppenheimer" is very very good and passes surprisingly close to the documented history. I was captivated.
My nerd credentials must quibble though: Those nixie tubes showing the countdown were not invented until 1955 (I know because a dear friend of mine, David Hagelbarger, invented them) and also the spoken countdown is plausibly credited to early broadcasts of rocket launches.
@robpike this caught my interest and went to search David Hagelbarger and see that they dont have a wikipedia page wich seems like quite a shame. I dont see any references to their work on Nixie tubes either. So interesting how many people fall though the cracks of history like that.
