So Melanie basically set fire to the tower infested with the seed pods and essentially DOOMED HUMANITY?
OK, so Melanie and those other children in the orange suits bound to chairs are technically the future of humanity, being able to think coherently and act normally despite having their brains infested with the zombie fungus and a craving for living flesh, and that they were developing in their mothers' wombs when the epidemic hit, and so thanks to the placenta were immune from the full effects of the contagion, and so they are our last hope for a cure, thanks to that doctor.
But then she is killed by the hungry children and so are all our protagonists, except for the teacher and Melanie, and so at the end the air is toxic to normal humans throughout the planet and the only teacher left is teaching Melanie's ilk from behind a glass airlock door? What happens if the teacher gets infected too? Will that be it? The children will grow up with no knowledge and the human race is doomed to be infected with the fungal virus with no cure AT ALL?? A bit downbeat, surely?
