The UPN network has cancelled teen alien drama Roswell. The show has been cancelled twice before and managed to garner enough fan support to come back from the dead both times, but this time the situation looks more critical. The series originated on the WB network, where fan intervention saved it from cancellation once. The second time the WB canceled the show, the UPN network picked it up. Perhaps the series can find a home on a cable network in the future, but producers Jason Katims and Russell Moore have written a final episode that manages to resolve the series' many ongoing plotlines, a sign that they don't think a third resurrection for the series is coming.
