For decades Hollywood has been remaking classic films. The hope is that those who saw them the first time around will check out the new version for the sake of nostalgia, bolstering the standard box office takings. Pulling this off for a film is one thing, but in the last few years US networks have taken on original UK series in the hope of replicating their success for an American audience. As this list shows, turning a TV show reboot into a hit is much harder than it seems because the viewers have to be compelled to return week after week. It is tough but not impossible. American classics, as recent reboots Dallas and 90210 have shown, can get a large amount of success. The first major US show to go in the other direction and get a British remake was Law & Order, which is went strong for eight series, regardless of the fact that Bradley Walsh is in it. Between those and The Office there is proof that the right team on the right project can bring great success. But that's not much fun. Most of the shows on this list were lucky to get past the Pilot stage, few survived to the end of their own first series and from those that did, not one received a second. So sit back and enjoy some of the worst reboots in TV history...
