I thought it was boring, and it should never have been made. I didn't care about any of the characters, especially not the robotic, wooden little boy.
I also didn't like how anything was explained, or concluded. Like the woman's immunity. It was just left unsolved and open. And then there was a massive explosion, killing absolutely everyone and everything, apart from Robert Carlyle. Is he some kind of invincible super zombie, who is resistant to fire bombs, and chemical weapons, and flame throwers?
A generous 2/10.
