A friend described Sandra Bullock's moaning and gasping in a good portion of the film as sounding like "bad sex." This was just a bad movie with no realism and, really, no suspense...the whole thing just wasn't believable. How Sandra Bullock's character was not screened out of the space program due to her emotional problems caused by the sudden death of her four year old child cannot be explained. George Clooney's character was a modern day Don Juan (apparently the only role Clooney is comfortable portraying) and is about as realistic as Johnny Depp's role as Tonto in "The Lone Ranger." Putting "the make" on a fellow astronaut during a life threatening situation is only credible to Hollywood. Sadly, this kind of fluff in now de rigueur in today's world of film production!
