Terrific documentary and makes you realise that there is more than tanks and nuclear warheads to worry about. I knew a bit about Stuxnet before I watched it but it was pretty mind-blowing. Modern life can so easily descend into chaos courtesy of a bit of sophisticated computer programming - and, dare I say it, the genie is well and truly out of the bottle.
