I don't know why people have been giving 5 stars to this show. It is not bad but it is extremely unrealistic and cringe.
The whole series makes Darius the hero and frankly he seems dumb. I understand the unrealistic part. It is based on the fantasy of an asteroid hitting the earth but other than that all the series of actions that take place are cringe and dumb.
This could have easily been ended in one season and not more than 5-6 episodes. They streached it too far and it kept getting boring.
