Just saw it and it was a good movie. I did read that a lot of people were a bit nauseous during the first 20 minutes or so...I can see why... I have had a bit of a stomach issue for the last two weeks and I had to be a bit careful to relax and look away a bit but I am glad I didn't see it 3D.
I enjoyed the film don't know how plausible it was but it was riveting.
Also Sandra Bullock looks absolutely fantastic ... hope it was all her and not some body double.
I did think it was a tad much at the very endbut it's a movie it did remind me a bit of the opening scene in Charlton Heston Planet of the Apes film for some reason.Click to see Spoiler:with the potential drowning
