I like that Nolan took an angle and stuck to it. Tell Oppenheimer's story.
The acting was impeccable, the audience was bombarded with movement and information without stop, to mirror the war moment... and possibly Oppis mind. Sound and lighting design was exceptional. Depicting human nature to turn on you for speaking your truth or anything it can get you on, but salute you for building a bomb, also done well.
4 stars only because human depth felt lacking... which seemed purposefully done but I'd prefer to feel moved.
