There are two stories: one is about how they managed to produce the first image of a black hole. The other is about a team of 3 theoretical scientists trying to solve the information paradox along with late Stephen Hawking.
They should have said more about details of both issues, i.e. how they designed the plan to solve both problems - that would have been super captivating. They focused more on people (as per usual Netflix approach) and their feelings.. anyway, still very good to watch on Sunday afternoon.
