One of the best lessons that Seinfeld taught TV networks is that it really isn’t important to have life lessons built into prime time sitcoms. 30 Rock has been a great torchbearer for that sentiment. The biggest emotional reach they decided to take in setting up this week’s season finale was to have Jack find his long lost biological father.In an attempt to generate more interest, the long lost father is in need of a kidney. Despite that somewhat lame cliffhanger, 30 Rock did try to deliver some season ending fireworks via a round of high powered musical guest stars.

After barging in on Jenna’s newfound stardom, Liz goes on a daytime talk show giving relationship advice. Despite being a total wreck herself, Liz is a smash hit. She hands out the same meaningless catchphrase “that’s a deal breaker” over and over to the delight of squealing women. Liz for the first time, is getting recognized.

While hesitant at first, Jack becomes enamored of his new found liberal father. After testing the two and finding their kidneys are not a match, Jack is off the hook. However, Jack has taken a shine to his new father and he pulls out all the stops to create a “charity” with the sole purpose of getting his father a kidney. Elvis Costello, Clay Aiken, Wyclef, Sheryl Crowe and a whole gang of others are assembled to awkwardly sing a crazy tribute to Jack’s father and his need for a new kidney. Its very funny and it was impressive to see all the musicians having fun playing with their public images.

Its was a good episode to be sure, but it seemed like a low note to end a season with. Though the episode was still better than any episode of Kath and Kim, I expected more as a wrap up to 30 Rock’s most successful season. Never the less, I hope we’ll get to see more of Alan Alda as Jack’s father next season. Plus the fact that a quirky and smart show like 30 Rock is safe from cancellation should be comforting. I hope we get to see Tina Fey and the rest of the writers feel some of the freedom that comes with that success and take a few more risks as well.
