It's nice to say that the last few episodes were "the best episode yet."
Without a doubt, this is where the show should have been all along. You know that they've got it right when the episode concept almost feels like it could have been an original Muppet Show episode. They added in the perfect balance of Muppet wackiness by not being too cartoonish with their disaster, letting characters show their classic best, and they showed Muppet heart without being sappy with Gonzo's pep talk to Scooter, Rowlf's pep talk to Kermit, and Kermit's classic solution to his stress problem. Seriously, Jason Bateman's annoying actions towards Kermit did wonders for the frog. He didn't need any of the New Age nonsense to be happy. He needed reminders of his old swamp.
And seriously, I knew that giant stick of butter was a good sign for the episode. It has been the funniest episode of the series so far without needing to rely on awkward jokes that, to be perfectly honest I was eh...barely alright with anyway. Bunsen and Beaker acting all Bunsen and Beakery? How about some more of that? This episode proved they can keep doing the show they're doing, and improvement slowly but surely came with each passing episode. Nice to see they kept the Janice and Sam thing going, so it's not just an awkward little side bit in one episode. So, continuity. Loved how Piggy was slightly more comfortable being around Denise, and loved even more how concerned she was about Kermie here.
Hopefully this episode is the AHA that the show needed and we'll go on to more slapstick that fits perfectly in a more grounded setting like this series. See? This is why I'm skeptical about the show getting a "retool." Seems that it's retooling itself quite nicely. Just keep up what made this episode great and discard what made the first 3 episodes awkward.
