It's "big miss" is the already admitted impossible "let go" of George Clooney's character Kowalski by Sandra Bullock's Character Dr. Stone. (When Dr. Stone let's go of Kowalski's hand Kowalski would not have floated off into the wild black yonder, he would have stayed exactly where he was. And, in fact, there was no reason to let go of Kowalski's hand -- all she needed to do was pull him back to the tether line ... because he's weightless. It seems that it's no big deal to the people who like this film a lot. Well, I liked the movie too but there are a lot of other ways that Kowalski could have "died" in the movie and any one of them would not have been as dumb as the one they used. (What if in "Gone with the Wind" Scarlett floated down the staircase instead of walking down the staircase.) But ... since this is a space movie such a dumb impossibility is forgiven.
