I watched Openheimer in a IMAX movie theater today, it was not bad I liked it, especially the cinemography.
But somehow - probably because I didn’t do enough research before going - I was expecting a lot of nerdy physics science like in the Martian, but it was mostly politics.
People seem to be missing the point it was a character study. Not a Manhattan Project movie nor a war movie. I wasn’t expecting the courtroom as I was only familiar with the Manhattan Project stuff and the movie wouldn’t be the same without those parts for the reasons you see well described.
