This movie was ruined by horrible writing. The only good thing about this movie is the actress who plays Gemma, but I felt bad for her because of how awful of a script she was given. The movie was so unrealistic, not just the science behind the world, but every character is portrayed in the most dramatic way possible. No one reacts or behaves in reality the way most of these characters do in this movie with out a proper explanation or reason behind it. Overall, this movie was nothing but two hours worth of cringe.
