As an overall, I don't feel this episode was horrid. I was somewhat taken aback but still very pleased to hear Kanto themes, such as when the judges are being introduced... IE, "The Matter's Settled" (that are very well composed by my opinion and have qualities that work well enough to create themselves) to be kept rather than remote in usage in the dub. Lots of emotional beats that are classy, aptly paced, but not methodical. Lots of nostalgia. :)
I liked a few of the dub pieces as well. They have a good, lucid quality to them, though I felt an abundance of it is a tad too trite and monotonous for my tastes. Dawn was very inconfident in tone in this episode, by contrast to May and Zoey, apparently, but at least she warmed back to her self at the culmination. At least it gives the character breathing space. And Team Rocket's.... Team Rocket. Mischievous, furtive, and skulking idlers at best. But more than the height of the episode, entertaining character interactions are what make it a draw-in in my eyes.
