Of all the spin-off TV incarnations of 'Star Trek, Deep Space Nine' had the hardest job persuading an audience to watch. By all accounts, Gene Roddenberry had concerns about the idea before his death in 1991. It took two more years to develop, and when it finally aired in 1993 reasons for that concern were evident right away. The show was dark (literally), characters argued a lot, no one went anywhere and the neighbouring natives were hardly ever friendly. Yet for all that the show went against the grain of The Great Bird's original vision of the future, it undeniably caught the mood of the time, incorporating a complex political backdrop that mirrored our own.
