CHICAGO -- Here's a question: What, if anything, can "Saturday Night Live" learn from the live episode of "30 Rock" that recently aired?
When "30 Rock" broadcast its first live episode in 2010, the experiment was interesting in theory, disappointing in practice. But credit to the sitcom's creators for cooking up another effort. Not because it was one of the show's best outings. It wasn't. But it was an intriguing example of what a live sketch comedy show could -- and, I would argue, should -- be attempting to do from week to week.
