After viewing the pilot, executives at the WB television channel decided not to put the series into production and it was shelved. The pilot only saw the light of day when it was "leaked" onto the Internet and distributed using the Bittorrent protocol (incidentally the first time an unaired pilot television program was released to the public in this way). Despite campaigning from fans, the WB stuck by the decision to pass on the series.
Sometimes referred to as 'the most popular show that never aired.'
Based on the popular DC/Wildstorm comic of the same name
