About
You’ll likely enjoy this thoughtful, true-story biopic if you like The Imitation Game or Creation and want drama driven by ambition, faith, and perseverance—not for you if you dislike stories centered on mathematics, heavy cultural conflict, or somewhat familiar biopic pacing.
Pros: Inspiring genius story; Strong lead performances; Cambridge setting feels vivid | Cons: Predictable biopic beats; Math may feel inaccessible; Some emotional/tone issues
