Is this show done?
I'd put this show somewhere in between Chappelle's show and Mind of Mencia on the watchability meter. It definitely had its moments, and David Alan Grier has enough experience that I would have given him a full season. I prefer it to Dimitri Martin, for what it's worth.
My main reason for liking this show is that it continues to carry out the awesome legacy of the "Bewitched" Movie, which was about an actor in a bomb movie resurrecting his career by playing the lead in a wildly popular TV show.
Stephen Colbert and Steve Carell are lead characters on wildly popular TV shows. Kate Walsh was on a wildly popular TV show, and has been given the lead on her new show. David Alan Gried was the 4th member of the cast to fulfill the Movie's paradoxical prophecy.
While it may have been a bit of an oversimplification to assume that giving an African American a sketch show in Dave Chappelle's old time slot could recapture the lightning in the bottle, it was definitely worth a try, and I hope I can at least catch all of the re-runs I missed.
