Forgetting about the critiques themselves, I liked the Washington Post's classification system for its fall preview so much that I made a table so you could easily scan it.
WaPo has mini-reviews for all the shows in the table. And people paying close attention will notice there are also a few shows from cable (Bored to Death, White Collar, and Sherri) as well as The Wanda Sykes Show.
