Virus is in the rain apparently. .if you step in a puddle or waterlogged ditch you catch it even if it's just wet your feet but they mosey on out 2 minutes after a rain storm because apparently rain wet trees, plants concrete doesn't contain the virus ...
Alternative dimension where the rules of physics don't apply? Maybe the last few episodes will tell me lol
William Goldman wrote some of the greatest screenplays in cinema history - Butch Cassidy & the Sundance Kid, Marathon Man, Princess Bride, Papillon, All the President's Men, Misery, etc etc etc. In his book, "Which Lie Did I Tell?" he said of reality in movies, "Do you really want to watch Mel Gibson drive around the courthouse for 45 minutes looking for a parking space?"
Lol... true. Don't get me wrong I am enjoying the series and the ever present threat of the "rain" .... it's just one of the clunkier pseudo science creations I've seen in a film/series.
