The fact that this show is popular enough to have spawned a full-length special and 20 hour-long episodes, when essentially the same thing happens in each one, is pretty fascinating.
This show depicts, in hi-def CGI fashion, a speculative version of what might happen if our species were totally annihilated and nature were to more or less reclaim all landscapes. Very little attention is paid to how people came to have disappeared in these scenarios (though some episodes suppose slightly different situations) and certainly no discussion of how we might stop that. Does this normalize the idea that we are inevitably wiping ourselves out?
