I don't like documentary style films either, but even if you disregard those parts, this movie is incredible. The filming is unsurpassed by anyone else in the ski industry, the cuts flow in a natural and logical fashion, the music kicks ass, the graphic design is tasteful, the entire film has a consistent design, I could go on.
One thing that really stood out is how he made graphics out of quotes and used them as chapter titles. Never seen that before, and it works amazingly well.
