The story was definitely unpredictable. They could have casted atleast a couple of macho figures in order for viewers to get involved into the CIPD character. I felt the officers were not as brisk as a disciplined force would be. RR & BGM is damn good. The prosthetics sucked at times; especially when you are making a zombie based movie, the prime selling element ZOMBIES could have been done well. I felt they were struck somewhere between the dead in the Pirates of the Caribbean and the white walkers from GOT... their eyes were very cheap looking. The weapons (guns) they were Using were so glowing as if it’s a high beam torch. Not to draw obvious conclusion but being a zombie flick, the background where the zombies were chained looked more like Walking Dead’s Season 2&3... the WOW factor is definitely missing, but you could watch for its storyline.
