Hmm. Seems it is goes into more of Hawkings like than Benedict Cumberbatch's "Hawking". (The latter only went into the first two years or so of his disease).
It seems to ignore that Hawking divorced however. (Hawking did only cover the first 2 or so years of his disease, so it did not come up in that show, though I think it was mentioned in the credits).
Though I do not think that makes him a horrible person or devalues what he achieved in his scientific career, or what he had to go through. But I think it devalues a movie a bit if it spins a fairy tale out of a real person's life. That has little to do (to me), with "hipster apathy" - I think it could actually make an interesting story to really learn how they fell into love, married, but then grew apart, him founding new love. But on the other hand - maybe it is not a story you can really tell with a man suffering from a rare disability that also happens to be a scientific genius. It could be a bit ... overloaded in terms of story.
If Hawking didn't exist and someone wrote a story about such a man, no one would believe it. It stretches the disbelief suspenders too much. "So, you tell me, this guy suffers from a disease that kills you after 2 years or so normally. But he lives to old age. And he speaks via a computer. And despite being paralysed, he has multiple children and wives. Oh, and he's a genius and a successful author. Too bad he doesn't fight crime, you could probably sell this to Marvel."
