Tyson is correct in every point he makes but he's missing the point. This was first and foremost a good, stunning movie. While I noted science quibbles in passing, it was hard to be preoccupied with them because I was fully engaged with the film. I do my worst nitpicking when I'm in hate with a film for wasting my damn time.
There's no sound in space. They stuck with that. I'm impressed so much by that one detail. What's more, read up on the notes the studio gave the director about things they wanted to see. They wanted flashbacks to Earth, they wanted Russians deliberately shooting missiles at the survivors and other silliness.
How would I rate the realism of this movie? It looks real-ish. Apollo 13 is hardcore real, only strained interpersonal dynamics were hammed up from what actually happened. But Gravity is a damned good film.
The only physics bit that bugged me was the tether scene. Spoilerish. Two astronauts tied together falling past a structure, once one of them grabs on and withstands the shock of the other astronaut snapping the tether taut, he should rebound back towards the secured astronaut, not dangle as if still being pulled by gravity. This would not be the case if, say, they were on a rotating structure or on a rocket making a significant burn but neither is the case.
