The Girl with All the Gifts (2016)

Plot hole: Based on Melanie's age and the state of decay of London, the world has been zombified for at least 10 years. Yet Melanie finds a small dog still alive inside an apartment which she uses to distract the hungries. The dog should have died many years prior.

Plot hole: Walking from Park Royal underground station to the base of the post office tower in central London is an achievement any day but to do it in a zombie apocalypse with no incident is a bit much to believe.
