There were some holes in the plot like;
In the movie, the people can only be get infected if they get bitten by a zombie which means the infection can only be transmitted through body fluids. So why the hell Gerry didn't transform to a zombie when he literally swallowed zombie blood.
Why was there a zombie in a closet inside a commercial plane,
Whenever they tried to be sneaky and not to lure the zombies some of them do dumb stuff and create noise.
How the hell the zombies managed to climb 20-30 meter wall.
Why the refugees felt the need to sing. I mean you are surrounded by zombies and you are singing weird songs to lure them. Pointless act to make zombie attack on Jerusalem not reasonless.
Non the less the movie was decent enough.
7/10
