Well, physics education definitely spoils Gravity somewhat. They tried to do bunch of stuff in realistic manner and crossed into "uncanny valley" of movie realism. During the movie I was "why medical doctor is servicing Hubble?", "no, you are not going to see it coming", "no, don't remove helmet when there is fire in the cabin!"
And, more importantly, "all three of them on the same orbit sequentially if they can go from one to another?". Basically movie implies that. Of course the question is how they got Hubble on the same orbit, since they where servicing it, by theoretically it could have been repositioned during previous missions.
