What keeps me coming back to this rather omnious movie is the part when Samuel Jackson's character defines his plan to combat 'climate change'. Sickening as it was, there is much truth to be said for reducing the population, carbon emissions, etc. Before the advances of medical science, 'nature' would cull via diseases, but now people are living longer and in some cultures and social circles, over populating causing more burning of fossil fuels and leaving a larger footprint on the planet than ever before. Just one great-grannies opinion.
