show is ok if you have no physics or general science understanding. Landing a space station, come on. Radiation that melts the ground people instantly but the people from the Ark not affected because 3 generations in space has evolved them to "metabolize" radiation faster. Come on. Not sending people to Earth because radiation might kill them, but it is ok to cull the herd, just send them to Earth, maybe they will live. Insane technology, but no radiation detector, come on. In an educated society, this show would be cancelled after season one.
P.S. over-used terms : "my people", "survive". The Walking Dead has enough of that, do not need more.
One interesting thing, show looks to a lot of ancient Greek mythology and folklore for plot lines.
