The new sci-fi

In The Guardian, Gareth McLean investigates the resurrection of TV sci-fi.

It can't be a coincidence that Lost, Heroes and Battlestar Galactica are laced with paranoia and suspicion - of government, of others, and, in Lost, of the Others. Just as Invasion of the Bodysnatchers in 1956 played on fears of reds under the bed, these are the times in which we live. [Tim]Kring [creator of Heroes] points out that heroes emerge in popular culture at times of crisis in the real world: Superman, for example, was born from the depths of the Depression. As Doctor Who supremo Russell T Davies notes, albeit while emphasising the optimism of his own show: "We live in a time of terror."
