While ratings began agreeably, by the end of the first season they were down significantly. During the second season, the ratings slowly rose toward the end; however, the show became increasingly expensive to produce at the same time. Many fans suspected that, due to HBO's tradition of carrying shows through to an end, and Daniel Knauf's six-year-plan, the show would be renewed, but in May 2005, it was leaked that the series would not be returning for another season. HBO confirmed that the show had been canceled on 11 May 2005. The show's ending after its second season and leaving so many plot lines unfinished has outraged many viewers. Some of them organized petitions and mailing drives to HBO to get the shows renewed. According to HBO's president this generated 50,000 emails in one weekend to the network.
