About
You’ll likely enjoy this if you want an uplifting, thoughtful documentary that mixes personal biography with big cosmic questions; Not for you if you want a purely science-focused deep dive or a smooth, linear structure like Red Army.
Pros: inspiring life portrait; mind-expanding ideas; accessible for non-experts | Cons: science depth uneven; abrupt topic shifts; can feel dry
