I want to vote for Space Girls because there really is something to hte idea that could have worked, especially in 1996/7, but boy did Bishop 'n Tomlinson not find the actual story to tell with the characters. Would it not have been enough just to have them loosely modelled on the Spice Girls' personalities, without also having to have some guff about manufactured bands?
Agree with Funt that the ending of Silo makes little sense, but for me the atmosphere of the opening three episodes or so are REALLY very good, and bless 'em, the Space Girls can't compete.
