I loved the movie. As you show quite well, there were so many aspects done right in this movie. Not an easy task at all.
I really liked how "Oppenheimer" the movie made it relatively easy to follow the many different and at times inherently difficult aspects, how all played out well.
I did some prep work before watching the movie at the scientific level, and that may have made it easier for me to enjoy the scientific parts (some not mentioned in the movie). Of course, it is weird to write enjoyment when talking about the Bomb.
I recommend the movie to anyone. I did not mind it was longer than most movies.
