This is NOT a horror move, but it's still good.

Rating: 7/10 (12 January 2019)

There are a ton of bad reviews on here by people who were disappointed that the creature horror didn't really deliver and answers weren't really provided. This isn't really that type of move. It's about people and their reactions to difficult circumstances and how they interact with each other.
It's really the story of the main character played by Sandra, and she does a pretty good job. If you are looking for straightup horror or a creature film this isn't what you are looking for. If you want an adventure story about the human spirit this movie will fit the bill.
7 is my honest opinion, I consider anything 6 or above worth watching.
