It only took eleven freakin' years, but we finally got our damn explanation about how the Elite 4 operates in the anime. Past Elite 4 members only really showed up for the sake of putting Satoshi in his place, only to never show up again. And while Goyou does the same to Buizel & Hikari here, we get actual insight into the E4 challenge and Champion that acts as potential but not definitive foreshadowing. I really do think it would be unfortunate if this build-up were all for nothing, but it was nice that after a decade of speculation, we finally learned how the quartet is challenged. And Goyou is a pretty cool guy, as was Dotakun quite literally pulling tricks out of its ***.
One thing that does disappoint me is that we see a potential rivalry between Greggle and Buizel here (you can see the hype regarding it in the earlier posts here), but it was never brought up again once. It's a shame as it could have proved quite interesting. It's also funny to see how people pegged Buizel as Hikari's version of disobedient Lizardon, when in reality, her version would come much later in the saga. My other minor complaint is that once TR enters the picture, the episode morphs into familiar E4 episode territory and ends fairly typically. But it's a pretty solid episode up until that point, and while the battle was basically a slaughter, it wasn't over in a flash or anything.
