The cast is full of unbelievable "intelligent" characters. If this is what Earth has to send to a new planet to save humanity then we may as well just give up now. Dysfunctional teenagers displaying PhD levels of medical and engineering expertise one moment - who make shockingly dumb and naive decisions the next, plus an idiotic motley crew of emotionally unstable 'adults'... it's ridiculous. This is another 'teenage girl an do it all' TV show, where they call the shots and save the day (or don't, but with no accountability) - this is Hollywood/Netflix, liberal America ramming their agenda down our throats, again! The concept of the show is great and has longevity, it's such a huge shame the makers/writers etc insisted on piecing together such unbelievable nonsense. Anyone with an IQ over 65, AVOID!
