I watched it in IMAX 3D with my brother who spent a year in Nepal. We are into the outdoors and climbing, but we both think these "hero" climbs (K2, etc) are dumb as fuck. So many senseless deaths. Foreign people monetizing the mountain, it seems insane.
In any case, I liked the film. Acting was great (the actor guy who plays the lead is the CIA guy from the Bin Laden movie with the girl from The Help. He's great.). It's really well shot, great performances from the cast, the 3D Himalayas are a trip on the giant screen. The movie is quite tense - I got anxiety watching it, chest pains even, as you see the disaster unfold slowly and are helpless but to watch it all go awry. It's horrific in certain scenes.
I'd recommend it if you are the adventurous type and into the mountains, etc.
