A rather good looking family decides they are so above some super necessary Malthusian laws that they pump out an illegal extra kid (on a dying, oxygen starved planet which is cooler looking aesthetically than any other sci fi television show on the air in recent history even if it is stolen directly from Blade Runner) smuggles their way through an unstable time rift to a prehistoric Earth straight off the Disney lot which is going to be super awkward when the inevitable happens and the asteroid ice age thing eradicates all life on Earth the way it did a gabillion years ago when it killed the dinosaurs and stuff.
There are hot teens in it, though, so it will probably be pretty popular.
wasn’t too fond of the cliche “I’m a hot teen that hate my family and I didn’t want to go with them on the family vacation cause i’ll miss my girl friend, but dont worry cause i meet a super cute rebelious girl that shows me a side of me I never knew” sidestory.
