Brilliant. Cerebral but a many-faceted story and history. It required 3hrs to portray the full story of Oppenheimer and his life; the creation of the atomic bomb and its impact on the world; the many people involved; the politics and subterfuge... If you want a fun movie this isn't it. If you want a rich historical movie that challenges your intellect and is rewarding in every way and is rich cinematically, then this is your film. There is genius in the writing, screenplay, script; acting; photography; costuming; music, etc. I'm glad I saw Oppenheimer.
