I was anxiously waiting to see this movie after it had been advertised. Finally caught it on HBO! I have really enjoyed watching Sandra Bullock in all the movies she has ever done and she did do an amazing acting job in this movie. However, I was disappointed with how fake and seemingly unrealistic the scenes were in the movie. There were several times that Bullock's character would have died due to extreme changes in pressure. I also thought Bullock's character could have been developed much more into a good story line. To me, the movie was just a series of events that did not create any realistic suspense. Unfortunately, sadly disappointed.
