I got this on NetFlix. Personally I thought it was pretty good. Not sure how realistic, but it did not seem too cheesy to me. BTW, if you are not familiar it is about an attempt to climb the North Face of the Eiger in the 1930s.
It is a great film on all levels. I saw it with some friends who were not familiar with climbing history but were still able to enjoy the drama and setting. I told them about the Eiger attempts ,the successful climb ,and the weird Hitler and Leni Riefenstahl connections .
