This is honestly the BEST show I've ever watched in my life. Definitely recommend this show for anyone above 13-15. Here are some reasons why: First, every character in the show is selfish, mean, and tough at the beginning, and there's not much good blood between them. Over the course of the show, the characters create bonds that are so strong some characters will do anything to protect them. Even though some parts are bloody and violent (especially the torture) its more of an emotional cause and effect placed circumstance for everyone. Themes such as "there are no good guys" or "let's do better" is repeated throughout the entire show, making it a lot more thoughtful and deep than your ordinary good guy bad guy film. Overall the show is so dynamic, changing from survival to refugee to outer planets, but it all goes together smoothly. The moral values and themes the characters have are amazing, and once you watch the show for yourself you will see why.
