It is based on real events. I watched it three times, and I felt a lot every time.

Naulo:

What is out of society? Christopher pursues a kind of freedom, being close to nature, leaving the noisy society and living his own life. However, is he really divorced from this society? Did he pursue the freedom he longed for? No, all the knowledge and tools he used to adapt to wilderness life are the products of modern civilized society. How can you survive in the wild without this? Christopher really understood the true meaning of life before he died. Only when his family, the people he loves and the people he cares about are happy can he spend his life with these people. This is the true meaning of life. Although the film is very sad and makes me feel sorry for him, such behavior does not allow me to support it.

This is my previous comment.
