I really enjoyed it. Thought it was actually better than "Walk The Swine" in many respects although I didn't necessarily dislike that episode. I just felt the whole thing flowed better, had sharper writing, and was truer to the characters while still advancing storylines (within the episode and for the series overall).
Great to have Denise back, and even better, great to have her a bit more well-defined. I felt something very organic happening in the scene that had her gushing over Kristin Chenoweth. There's a little bit of nerd-fangirl to Denise that could work well in future episodes if the writers are willing to keep pushing that.
Smart work with the Kermit-Piggy dynamic too. I had a feeling Piggy would find a way to slip in some mild sabotage with her gift (the look on Kermit's face when he heard the jewelry-box song was PRICELESS, followed perfectly by Piggy's "That is MESSED UP!" topper line). The promos had me worried that it would be yet another jealous-Piggy freak-out. Great to see a better fleshing out of that plotline, especially the scenes with Kermit trying to make the best of things at Color Me Mine and stalling with the "extra verses" of "Happy Birthday."
Kristin C. brought a wonderful energy to this episode, as is typical of her appearances in other media. I almost wish they had used her a little more extensively, which I expected to happen after she and Piggy did their duet. The scenes with her on the EM bus were a hoot and I'm glad to see the Floyd-and-Janice pairing got a minor subplot of its own. I think the actual production of the band ditching Kristin in the desert could have been more effective - it left me a little cold, and not just because of the green-screening. But overall, great use of the EM this week. ("Animal LOVE to perform with live snakes - but Zoot big baby..." bahaha...)
The supporting players are KILLING IT! Scooter and his Mom ("Put a ROBE on, Ken!"); the writers'-room guys and Chip coming up with terrible gift ideas; Pepe (e-mail address!), Rizzo and Gonzo in the closing sequence; Uncle Deadly "I don't offer solutions, I just dramatize problems"...I'm sure I missed some of the lines because I was laughing so hard at others. It's like my experience with the first decade of The Simpsons, honestly.
Everything and everybody felt pretty much spot-on this week, and I didn't mind Fozzie getting a breather after he had taken such a big role in the previous five episodes. Looking forward to next week already!
