Good movie, but so many questions without answers. 1. Why did the boy throw the woman off the boat. She saved his life. There are no answers anywhere to why? 2. Why did the boy try to kill himself, or so it seemed? 3. Why did he throw all her bottled water in the ocean when he knew how far they were from anyone. If someone could please answer these questions in a review, that would be very helpful. Overall, I enjoyed this movie. I am still thinking about it. It was very well made movie with excellent acting. Addresses many unknowns and will keep you thinking and thinking after movie is over.
