I went to see 127 Hours after going back and forth for two days trying to determine if I could watch someone cut their arm off to survive. I am glad i did, as it is quite an amazing movie on several levels. The personal story told by the actor representing the man who had to do this in real life was revealing and very reflective.
If you can stand the scenes where he breaks arm bone and cuts off his own arm with a dull knife, go rush to see it.
