Loved it ..... Mostly in zombie movies,we get a similar origin like there was this virus and it started spreading..bla bla bla... But this was something else. There was lot more in this series. You get to see a different setup and a brilliant story. Ending was tricky. They made it a simple and fully focusing on the story. Like in movies there are two endings
One a hero saves by doing everything he can,he somehow manages to defeat the villain with all the resources he have. Second is that hero don't have any resources but try 's his best to beat the villain and lose the battle. But we see in this series that the hero had everything with him to beat the villain but he had his personal problems too. He managed his problems and also the world's problem with him. At last he solves his problems but gets late to solve the world's problems.
