The 2003 debut of Chappelle's Show on Comedy Central marked a high point for the cable channel, and now the entire, wildly creative first season can be seen, with hundreds of bleeps removed. That's not to say Chappelle's Show is perfect entertainment: there are too many moments among the 12 episodes here that descend into pointless scatology and booty fever. But for the most part, Chappelle, a talented comic slowly growing into greatness, is trying to push the sketch-humor envelope and succeeds at surprising US with original concepts and merciless execution.
