While there is one thing I can agree is totally different about the new series vs the old series, it's the humor. It's new humor, clearly. Everything is a product of the time it was created, no matter how much anyone denies it. This episode really felt like the writers were trying to blend new humor and classic PPG humor, and I think they were successful. This is one of my favorite episodes so far, right up there with the Beauty Pageant episode and "Arachnolove." Blossom is much more like her original character here and less obsessed about organization and cleanliness. Meanwhile Bubbles and Buttercup are bringing the new style of writing to the table fabulously to counterpoint the episode's A story, which is something that totally wouldn't be out of place in the original series. Especially the bit about how the teacher was always a centaur to begin with. Love the bit of lampshading at the end about how it would just have been easier to develop something that changed him back into a human. It really seems that this episode is starting to show that the writers are trying hard to balance their writing style and the style of the original show. Writing is based all on bias. Writers have favorite jokes, references, and themes. The new series writers have a different childhood than Craig and Genndy and others who worked on the other show. Heck, they were inspired by that show. That's why the show feels a might off, it's copy of a copy. A good copy, IMO, but still a little fuzzier.
