The ending...[Spoilers]
I liked this film. Had a definite 28 Days Later vibe. However, the ending puzzles me:
How does Justineau (Gemma Arterton) survive in the airlocked laboratory? She can't go out, at least until the spores go away, (whenever that might be) and even then she would probably be bitten by one of the hungry children or an adult "hungry". Is there a never ending supply of food and water inside? Is the girl going to bring her dead animals to eat and somehow get it inside without contamination.
Any ideas? Maybe the novel has some clues.
