This is a great Sci-Fi show that most Tweens and teens will love. There are tons of positive messages; the entire show is based on positive role models and messages of sticking together, not being greedy, the love between a family, help others, saving the environment, watching out for ourselves, others, and the environment, and the list goes on and on. Basically, colonists are sent (with supplies) from the year 2149, where the earth is dying, back to the age of the dinosaurs to rebuild the human civilization. The story follows the Shannon's, who will do anything for one another. With an army officer (Stephen Lang) as one of their leaders, they seek to save the earth. There is violence related to protecting themselves and the colony from dinosaurs; characters carry guns, tazers, etc. Also, there are tanks and various intense scenes in which humans with big guns face off carnivorous dinosaurs. There is kissing between teens as romances blossom, and there is also minimal drinking. There is some moderate language; *ss, h*ll, d*mn, b****rd, and SOB are used in the show. They are used in scenes of fear, pain, frustration, anger, etc. This show is great for teens and up (and for mature Tweens).
