As a show this is great. I watched in one afternoon. A good continuation in the Jurassic World theme. Characters are good and the story keeps you guessing. Continuing to give the dinosaurs personalities is a good way of telling the story with the main characters interacting with them.
But the themes are way too mature. People die including an adult close to one of the main characters. Characters often fear they would lose their lives or deal with the guilt of losing one of their own. Betrayal and verbal threats are part of the storyline. 9 to 7 are too young to be dealing with these themes on their own.
