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.
Wife and I had a similar experience. We kept thinking “oh, here’s the part where we’re going to talk about all the science and physics!” but then went off on another track. I liked it overall though and have generally been a Nolan fan.
