not as good as all the hype. sure Sandra is worth watching but the overall movie wasn't brilliant. Not a fan of George but without his voice (yes, his calm and soothing voice) it wouldn't have been so watchable. There were a few ‘hurry up’ moments where you think there is no way you would stop there if that was a real situation. I understood a lot more after watching how it was made. Details you don't register while watching the movie but later realise how important they are.
