The reason why a lot of people didn't like this series is because they thought it would be a show about a woman surviving in the wilderness. That's it. But the real survival is the one she struggles with inside, and every event that happens in the wilderness plays a part in her letting go and getting through her trauma from childhood to adulthood. There are a lot of flash backs. But it's vital to why she keeps waking up each day and pushes through to keep alive.
First it's about being tough.
Then it's about finally freeing yourself of the pain you hang on to.
And also: The videography and scenery are beautiful. The music on point. It was a gorgeous show that deserves more than the low reviews. Don't be afraid to watch it- you might cry like I did at the end.
