Clearly what fans of the sci-fi genre.

The series takes place on an end time Earth after an alien invasion. In certain various alien races and people after a war to fight the remaining resources.
The pilot is well done and worth seeing in any case, especially computer animation and like masks of the alien races.
Unfortunately, the consequences are then rather barren and can just as well in a '80s Western series play. Good Sheriff protect good citizens from bad guys, spiced with some racial conflict, intrigue and love with very predictable plot. As one should expect in 2013 so today a bit more excitement to series like Game of Thrones.
But clearly defy what fans of this genre therefore 4 stars.
