It wasn’t a terrible film. The central figure experienced a difficult and isolated existence, and I felt considerable sympathy for her. However, after the airplane went down in the water and she made it to shore on an island, she discovered she wasn't by herself. Her supervisor also ended up on the island; he was hurt, and she assisted him in recovering. Because she enjoys "Survivor" series, she exerted every effort to endure their circumstances. Interestingly, she seemed content with her situation on the island. There were opportunities for them to leave, but she chose to remain with her boss. She even took a life, which is when my opinion of her shifted. Her actions were wrong; I can’t fault him for wanting revenge, and frankly, I probably would have reacted in kind.
