This is great. I kept laughing at his novice blunders because they reminded me of my childhood mistakes learning about hiking. I kept saying, "Dude, what are you doing?" And "God, don't do that." He brought back so many memories. And then, the movie conveys his growth in character from his experience and yet still leaves a novice. Unless you're a hiker, you'll miss most of the humor or appreciate the journey the movie conveys.
