What is that red stuff growing everywhere?

Went and saw the remake of “War of the Worlds”:http://www.imdb.com/title/tt0407304/ last night with Will. I left the cinema with more questions than I had before the movie! I won’t go into details for fear of spoiling it for anyone else, but I guarantee if you _do_ go and see it you will leave with many questions, undoubtedly including the title of this post! Good edge-of-your-seat movie, Will gave it 6.5/10.
