There's not much else to say about this one, really. Years ago the movie Hilary and Jackie also dealt with a (music, in that case) prodigy whose life was devastated by a terrible, disabling sickness. It WAS about the sickness, but it was also about real people and family dynamics. I found that approach quite intelligent, even edgy at times, though back then some complained that it was still too "soft". What would they say about The Theory of Everything then?
And it's not, by the way,that even here there wouldn't be potentially interesting aspects - especially in the second half of the movie, with the failing of the marriage and the debates about God. But they are treated in the most predictable, light way - and not only the two main characters, but everyone else is so... "saintly", so smiling and serene. It's such a flat movie (and one that, in the much more cynical 70s, would have instantly become the subject of countless, and politically uncorrect, parodies).
I said, about The Imitation Game, that while it IS about a gay person - and that's mentioned often in the film - one doesn't get the "feeling" of homosexuality. In The Theory of Everything one doesn't get the "feeling" of sickness - yes, they show the effects it has on the body, but not the deeper, less obvious psychological effects, both in the disabled person and in those around him. They are all just too adorable,
As for the two leads - at times it seems like when, in acting schools, you see young actors playing "mature" roles - there's something too juvenile about them (which becomes even more evident when their characters get older). At least the boy has the physical task to face - and that's the kind of task that the Academy always honors with a nomination, and often - though maybe not in this case - with a win. But the girl, a Susan Strasberg lookalike that I've never seen before and will probably never see again, is really unimpressive - I wonder how she can get a Best Actress nomination and, say, Marion Cotillard won't, but that's what will probably happen.
