'Thursdays go Goth' pairing <i>Supernatural, Vampire</i> The CW's hot new Twilight-tinged series The Vampire Diaries is kicking long time resident Smallville off of Thursdays, while pairing up with Supernatural, the network announced in the upfront presentation of its 2009-'10 schedule on Thursday. Meanwhile, the network canceled Reaper, as expected, though it's unclear if the show will live on in first-run syndication. "Thursdays go Goth" is one of The CW's new taglines. The Smallville/Supernatural pairing on Thursdays has been a staple on The CW for years, with the DC Comic-inspired Smallville doing fairly well and Supernatural building its ratings despite the worst competition on TV (it airs opposite Grey's Anatomy and CSI). Both shows had already gotten pick ups from the network.
