Comedy Central continues to make its name as the watchdog to the straight news. With Jon Stewart's ''The Daily Show," David Spade's ''The Showbiz Show," and now ''The Colbert Report," the network is providing viewers with a happy little cynicism hut where you can get takeout mockery and a side of gall.
''The Colbert Report" joined Comedy Central's lineup on Monday at 11:30 p.m., and it was an auspicious debut. The show, starring ''Daily Show" regular Stephen Colbert, could turn out to be a strong follow-up to Stewart's more conventional half-hour, forming a late-night hour that creeps from the sardonic into the fully warped. While Stewart keeps one foot on Earth and rolls his eyes skyward, Colbert skyrockets into absurdity as an out-and-out parody of a celebrity commentator. With his blowhard vocal pattern and patriotic pretenses, he's a living, breathing caricature of Bill O'Reilly.
