Me personally, I fail to give this movie 10 of 10 votes because of the simple fact that Dr. Ryan Stone cannot really be called a "specialist". Where did she get her Dr. from and in which subject? medicine? yeah right...which "mission specialist" says "enemene" when she tries to navigate a space capsule? which "mission specialist" has to read an instruction manual for a capsule that she possibly used on a daily basis? Even if not THIS capsule, most of these capsules are probably quite similar to handle. So I really doubt that something like that would give a real "expert" that much trouble. I think "Gravity" really failed in this regard. The other aspects of it are great...otherwise it's a great movie with a great story worth to see. But I still refuse to call Dr. Ryan Stone an "expert". There's simply no way for me to do that at this point.
