On the heels of the announcement that the series was picked up by NBC for a seventh and final season, 30 Rock aired a staggeringly average episode in "The Return of Avery Jessup."

The originality and creativity involved in recent outings such "Live From Studio 6H" and "Queen of Jordan 2" make them inherently divisive. People will either respond well to such comedy... or hate everyone for putting it on their televisions.

On the other side of the spectrum is an episode like "The Return of Avery Jessup," which seemed impossible to love or hate, because it was just so run of the mill. If you enjoy watching 30 Rock, you probably thought this was fine. If you don't like 30 Rock, why are you reading this review?

As I've said a number of times before, 30 Rock is such a great show because even when it doesn't fire on all cylinders creatively, there are always enough jokes to make it a worthwhile 30 minutes.

Even though Jenna's wedding sponsor plot wasn't overwhelmingly funny, it gave us Tracy's made up Bronx language, along with Kenneth showing Jenna how to walk like a southern hick.

While I didn't get fully invested in Jack and Avery's mental battle upon her return, I loved every cut away to the fake news in Korea. I mean, Kim Jong Un winning NBA games? The constant reminders that Kim Jong Il is still alive?  That was great stuff.

And finally, I could care less about Liz and Criss's relationship issues, but we still got Lemon's "Duck?!?!" as well as her Prime Suspect hat. As you see, hitting on a number of one-off jokes can make a any episode of 30 Rock worth your time.

Was it worth your time? Was this a mediocre episode of 30 Rock, or was it your favorite of the season? Are you excited that the show is coming back for season seven, or upset that it will be the final one?
