I was prepared for the intensity of 127 Hours, the movie based on the experiences of the hiker who got his arm caught in a boulder and had to saw it off with a pocket knife to save himself.
The movie was very well filmed and executed. It sustained the tension and momentum, even though it had such a simple narrative arc, and even though you knew the ending.
I had major shpilkies throughout, and couldn't watch the part where he actually cuts off his arm. In spite of that, it wasn't quite as horrific as I expected (the hallucinations weren't exploited for horror effect, and the sense of starving and dying of thirst were not quite as intense as I thought it would be).
James Franco was excellent, and it's definitely a good flick.
