I would say that the movie has potential. The design with the zombies is actually not bad. And the action is good. The MC is actually badass at the beginning until the mid of the movie.
But it start to not make sense when the car exploded when Singh is surrounded by the zombies. Like, how did Sighn not died from the explosion?
And also, at the rooftop, at the helicopter scene? Why did he not just went to the helicopter if he is not infected? Why did he wait for so long? It doesn't make sense. It is so poor writing.
It is as if they are trying so hard to make the MC look badass. And at the end, he did not die from the Massive explosion. IT DOESN'T really make sense. It went from 8/10 to 1/10 real quick.
This movie suck. Stupid writing from the script writer and the director.
