On the surface this is a goofy adventure where the kids see dinosaurs. But a lot of dark themes and trauma are explored in this one.

Jake almost dying (again). Cassie kills. Tobias and Ax choose genocide. Rachel....well actually our resident Miss Murder is actually fine. (Honestly she's thriving). And of course the kids look on as they contemplate their own annihilation and a world-ending event as they witness 66 million years of Earth's history flash before their eyes. 

This series really is at its best when its exploring the physical and mental trauma that these little child soldiers are going through.
